This paper presents a new method of improving the disturbance-rejection performance servo system based on estimation an equivalent input disturbance (EID). First, concept EID is defined. Next, configuration improved employing disturbance-estimation described. Then, designing control law estimate explained. Finally, speed rotational used to demonstrate validity method, and some design guidelines are presented.
A fail-safe sequential machine is one that produces safe-side output when failures occur in the machine. This paper presents a new method of realization machines under following assumptions: 1) failure caused by single fault element machine, 2) faulty stuck at or zero, and 3) input does not malfunction.
e-Learning engineering courses with online experiments are attracting a great deal of attention because the flexibility they provide in both teaching and learning. This paper has described an Internet-based experiment system for control (ITESCE) that provides students course material, simulator, using arm robot, ability to store search simulation experimental results. To implement functions required by facilitate connection Internet, ITESCE is based on standard browser/server architecture...
Abstract In recent years, IoT technologies have made our daily lives more convenient and comfortable. particular, these are being actively utilized in living environments through the development of various smart home appliances. As pace Digital Transformation (DX) quickens digital platforms become integrated into diverse residential settings, notion we inhabit is taking on greater significance beyond merely a place for rest. Therefore, this paper explains user-friendly interfaces systems...
<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper describes a simple effective approach to vehicular steering control based on the estimation of an equivalent input disturbance. A system configuration with disturbance estimator and design method linear matrix inequalities are explained. The simulation results demonstrate validity method. </para>
This paper proposes a new approach to disturbance estimation based on curvature model that improves the rejection performance of servo system. The main feature is stability control system guaranteed when estimate incorporated directly into designed law. Experimental results show disturbances are rejected efficiently this used.
This paper classifies human body movements when an electric wheelchair was controlled using a Human Body Motion Interface (HBMI) by Self-Organizing Map (SOM) and proposes control based on classification results. The uses movement following voluntary motion. study focuses as application of the HBMI. viability HBMI confirmed Center Of Weight (C.O.W.) from pressure distribution information backrest in to it. If concentrated single point at C.O.W. distribution, problem occurred because system...
This paper presents a new method of improving the disturbance rejection performance servo system by estimating an equivalent input disturbance. First, concept is defined. Next, configuration improved employing estimation described. Then, designing control law estimate explained. Finally, positioning two-finger robot hand used to demonstrate validity method.
This article presents a method of suppressing packet losses and exogenous disturbances for networked control system (NCS) subject to network-introduced delays. The NCS has two feedback loops: 1) local one 2) main one. loop contains state observer, an equivalent-input-disturbance (EID) estimator, feedback. It is used ensure prompt disturbance suppression. controller in the internal model track reference input. divided into subsystems design controllers. state-observer gain designed subsystem...
A fuzzy-control strategy for the control of an acrobot is described. The combines model-free and model-based fuzzy control. controller designed upswing ensures that energy increases with each swing. law torque derived directly from acrobot. controller, which based on a Takagi-Sugeno model balancing, employs concept parallel distributed compensation. stability system balance guaranteed by common symmetric positive matrix, satisfies linear matrix inequalities found convex optimisation technique.
This paper presents a user-friendly hand force feedback system to recognize surrounding obstacles around the elderly making walking safer. The is implemented on joystick mounted walker. user able spatial information from repulsive generated as joystick. based generation of virtual potential field that corresponds distance and direction obstacle employed. Through experimental results, it found practice time learn basic operation sufficiently short. Furthermore, feels sense security while...
This paper proposes a control algorithm for robotic swarm based on the center of gravity local swarm. In order to be compatible with maintaining high stability whole and advancing goal, virtual forces; forces an force which are produced by algorithm, applied multiple autonomous mobile robots. Local such as attraction repulsion, each robot increasing Overlapping partially increases The is goal while Since obstacles prevent considered disturbance from viewpoint swarm, effectiveness in obstacle...
This research studies the possibility of an intuitive interface for electric wheelchair by using human body except hands. For this purpose, we focused on motion which has relation to actions or behavior. comes from stabilization function holding expectable collapsing caused voluntary motion. Thus is considered as a kind characteristics motion, and linked intentions unconsciously. Therefore, does not require conscious complex realized applying wheelchair. In paper, first, did experiment...
This research develops a machine's interface which has features of universal design and offers an intuitive operation for complex tasks. We set the development electric wheelchair as practical example, proceed with this research. The joystick is general wheelchair. user needs to operate it in accordance operational procedure specifications. Therefore convenience system side rather than focus on body motions humans have, try realize new type replaces conventional joystick. time-series data...
This paper proposes a method that human and swarm robot move cooperatively so as to maintain the situation surround moving human. is concerned with control for maintaining high stability of swarm, algorithm robotic in obstacle space. In this paper, which includes whole robots defined swarm. addition, each neighboring forms local overlapped other ones partially, can belong some swarms. The proposed overcoming above problems based on center gravity attracts it, applied omni-directional mobile...
This paper presents a robot partner development platform based on smart devices. Humans communicate with others the basic motivations of human cooperation and have communicative motives social attributes. Understanding applying these become important in socially-embedded partners. Therefore, it is becoming more to develop robots that can be applied according needs while taking communication elements into consideration. The role not only industrial sector but also households. However, seems...
This paper explains the development of a new-concept three-wheeled electric cart that not only is means transportation, but also provides driver with way getting some physical exercise. Based on an investigation physiological decline accompanying aging, pedaling was chosen to implement function maintaining or improving strength; and ergonomically designed pedal unit mounted cart.
