Wireless control system (WCS) refers to the feedback control system with state and (or) control information transmitted over wireless channels. The control system stability is severely affected by the wireless transmission reliability, which in turn relies heavily on the scheduling of limited wireless communication resources, such as channel, time and power. Therefore, co-design of control stabilisation...
Adaptive tasks scheduling via feedback is an effective solution for the optimization of closed-loop control performance under computing power limitation, as in the computing nodes of embedded networked control systems. The problem of the feedback scheduling of a set of Linear-Quadratic controllers, based on both plant-state and resource utilization measurements is considered. The proposed feedback...
Continuous optimal linear quadratic control theory is adapted for the problem of optimal data transmission scheduling from base station to mobiles, in wireless CDMA based systems. Such discrete event scheduling problems have traditionally been treated within the computationally unwieldy, analytically difficult framework of multi class queues (e.g. cmu rules and their generalization (Van Meighem, 1995))...
This paper presents an adaptive gain scheduling control strategy for vehicle suspension design. A quarter car suspension model with a nonlinear dynamic model of the hydraulic actuator is employed. The feedback control gains of the controller designed using a combination of LQR control and nonlinear backstepping techniques are adapted to the changes of road input in order to provide optimal suspension...
