The paper considers robust H2 control problem of continuous-time interval state-space systems. A necessary and sufficient LMI-based condition is derived for analysis of quadratic stability and robust H2 control. Using the analysis result, a state feedback controller and a static output feedback controller can be designed so that the closed-loop interval state-space system is quadratically stable and...
The problems of robust Hinfin tolerant control for a class of discrete systems with state and time delays and actuator faults are studied. The T-S fuzzy model with time delays is adopted to repress a class of discrete systems. By established actuator fault model, the state feedback controller is designed. A sufficient condition for the asymptotic stability of closed-loop system is given based on Lyapunov...
A novel T-S fuzzy model-based method is proposed for controlling a class of chaotic (hyperchaotic) systems with uncertain parameters. The interval matrix theory is applied to describe the parametric uncertainty. The T-S fuzzy model is employed for accurately modeling the chaotic (hyperchaotic) systems. Based on the T-S fuzzy model, the parallel distributed compensation (PDC) technique is applied to...
Disturbance observer (DOB)-based controller design is one of the most popular methods in the field of motion control. This paper presents a design method for the disturbance observers to satisfy closed loop performance specifications, provided that the main feedback controller is known. Unlike the conventional methods, the proposed DOB design method takes into account the influence from not only disturbance...
