In this brief, a disturbance observer based prescribed-time tracking control strategy is proposed for class of high-order nonlinear systems with non-vanishing uncertainties. A finite time function firstly introduced to facilitate the and controller design. Then, constructed estimate compensate uncertainties, which ensures that estimation error converges zero in prescribed time. Based on backstepping design framework, further designed form scaling error. Theoretical analysis reveals achieves...
Parametric uncertainties and unmodeled disturbances limit the tracking performance improvement of DC motor systems. In this paper, a third-order continuous adaptive integral recursive terminal sliding mode (3-AIRTSM) control scheme is formulated for high-performance motion motors. The residual parameter are synthesised as lumped uncertainties. Then, derivative analysed whose upper bound denoted by system state signal dependent terms with unknown coefficients. Meanwhile, novel structure...
Each balance authority (BA) in a grid conforms to schedule that sets forth how much capacity will be allowed pass through the area at given times of day. However, because wind generation is variable and non-dispatchable source energy, it causes additional unscheduled deviation interchange complicates problem system balancing. Thus, BAs need procure more fast regulation meet Control Performance Standards (CPS) requirements. A fast-response storage device with appropriate duration effective...
A novel cellular learning automaton traffic flow model is proposed to solve the problem that probability of randomization in NaSch not consistent with actual traffic. The mechanism introduced this model. Cellular can learn information from neighbors real time. environment information, such as, relative speed and safety distance will be parallel ruler through form after learning. Finally numerical simulation, space-time characteristics were obtained, comparison analyzed. results show improved...
Abstract This article investigates an event‐triggered adaptive estimated inverse control scheme for uncertain nonlinear systems with hysteresis effects, parametric uncertainties, and unknown disturbances. An online compensation mechanism is developed, in which technique designed to obtain the value of parameters. Compared common approaches, its biggest advantage lies fact that it eliminates need experimental determination parameters, thereby reducing time‐consuming offline identification...
Abstract In this paper, a novel trajectory tracking control problem of the quadrotor UAV is addressed, which considers system uncertainties and unknown external disturbances meanwhile. To ensure rapid convergence rate states, fast terminal sliding mode (FTSMC) algorithm improved combining with fractional order method. addition, finite‐time observer designed to handle enhance robustness system. The closed‐loop stability established using Lyapunov theory in accordance law. evaluate...
In this paper, partial transient liquid phase (PTLP) diffusion bonding between Si3N4 ceramics and Ht250 cast iron was carried out by using an Ti/Cu/Kovar/Cu/Ti interlayer. The effects of the heating temperature holding time on microstructure, formation mechanism, mechanical properties Si3N4/Ht250 joints were studied. results show that maximum shear strength joint is 112 MPa when welding 1000 °C 1 h. addition, problems Ti/Cu/Ti intermetallic compound Cu/Si3N4 ceramic residual thermal stress...
An adaptive estimated inverse control methodology for a class of uncertain nonlinear system subjected to unknown Prandtl-Ishlinskii (PI) hysteresis nonlinearity is studied in this paper. The largest difficulty the compensation mechanism lies that its parameters are hard determine. To obviate such obstruction, online by techniques together with parameters. Thus, effects as well parameter uncertainties can both be suppressed without time-consuming off-line identification. Meanwhile, tracking...
Accurate estimation of the dynamic states a synchronous machine (e.g., rotor s angle and speed) is essential in monitoring controlling transient stability power system. It well known that covariance matrixes process noise (Q) measurement (R) have significant impact on Kalman filter performance estimating states. The conventional ad-hoc approaches for are not adequate achieving best filtering performance. To address this problem, paper proposes an adaptive approach to adaptively estimate Q R...
