A novel adaptive fuzzy trajectory tracking algorithm of Stewart platform based motion platform is proposed to compensate path deviation and degradation of controller’s performance due to actuator torque limit. The algorithm can be divided into two parts: the real-time trajectory shaping part and the joint space adaptive fuzzy controller part. For a reference trajectory in task space whenever an...

A compensation scheme is proposed for plants subject to both saturation and backlash in series at the actuator. It is shown that the series connection of a backlash inverse, saturation and the backlash itself is equivalent to a saturation function at a different level to the original saturation; we call this the ‘saturation equivalence’. Therefore it is proposed to include such a backlash inver...

Dept. of Electrical Engineering, University of Engineering and Technology, Lahore, Pakistan Correspondence author: [email protected] ABSTRACT: This paper deals with the state feedback  H stabilization problem of discrete-time 2-D (two-dimensional) switched systems subject to actuator saturation. Firstly, a sufficient condition for asymptotical stability and  H disturbance attenuation pe...

Based on discrete event-triggered communication scheme (DETCS), this paper is concerned with the satisfactory H ! / H 2 event-triggered fault-tolerant control problem for networked control system (NCS) with α -safety degree and actuator saturation constraint from the perspective of improving satisfaction of fault-tolerant control and saving network resource. Firstly, the closed-loop NCS model w...
