Voice coil actuators are extensively employed in precision motion applications with benefits including compact form factor, linear force behavior, and smooth operation. Adopting an optimal approach the design of this actuator can reduce size, manufacturing assembly costs, increase its bandwidth. Besides, having a model that captures nonlinear aspects could play significant role The development high-performance controllers. In paper, optimally-designed voice is developed characterized. Main...
Cylindrical Voice Coil Actuators (CVCAs) have a wide range of applications in various industries, especially the field precision motion applications, due to their simple structure, small size, lack backlash, and force ripple-free operation. Most often, actuator is required track periodic trajectory accurately. Hence, designing digital controller achieve zero tracking error presence plant uncertainties, high importance. In this paper, physics-based model previously-designed optimal VCA...
Activity recognition plays a crucial role in health monitoring systems. Most of our vital parameters like heartbeat rate or blood pressure are dependent on the activity we doing at time, and without knowing that, it is hard to figure out anomalies. Besides, can help us detect emergency situations falling, even heart stroke. Knowing importance detecting unusual activities (, e.g. falling) usual walking), this research has investigated possibility fall Activities Daily Living (ADLs) by three...
Tracking performance of voice coil actuators is often utmost importance in precision motion control applications. The focus this paper the design and implementation a digital system capable tracking pre-specified trajectories with high accuracy. After describing main components actuator system, an empirical model open-loop plant obtained, based on which PI controller designed to close loop. Then, closed-loop empirically obtained used for model-based design. Two approaches are employed meet...
