Fuzzy gain-scheduling output feedback controller design for saturated linear plants

引用

Journal of Harbin Institute of Technology(New Series) 2012年第6期19卷 79-86页

作者：班晓军邓宗全吴奋黄显林 Postdoctoral Research Station of Mechanical Engineering Harbin Institute of Technology School of Mechanical and Electrical Engineering Harbin Institute of Technology Dept. of Mechanical and Aerospace Engineering North Carolina State University Center for Control Theory and Guidance Technology Harbin Institute of Technology

In this paper, the control design problem for linear systems subject to actuator saturations is considered. A fuzzy gain-scheduling output feedback controller is proposed to guarantee the stability of the closed-loop system as well as providing disturbance/error attenuation measured in l2 norm. The synthesis condition is cast as a convex optimization problem in terms of linear matrix inequalities (lMIs) and can be solved efficiently. The ball-beam system is used to demonstrate the proposed saturation control approach.

This paper carries out an analysis of the l2 gain and l∞performance for singular linear systems under actuator *** notion of bounded state stability（BSS） with respect to the influence of l2 or l∞disturbances is introduced and conditions under which a system is bounded state stable are established in terms of linear matrix inequalities（lMIs） .The disturbance tolerance capability of the system is then measured as the bound on the l2 or l∞norm of the disturbances under which the system remains bounded state stable and the disturbance rejection capability is measured by the restricted l2 gain from the disturbance to the system output or l∞norm of the system *** on the BSS conditions,the assessment of the disturbance tolerance and rejection capabilities of the system under a given state feedback law is formulated and solved as lMI constrained optimization *** viewing the feedback gain as an additional variable,these optimization problems can be readily adapted for control *** analysis and design reduce to the existing results for regular linear systems in the degenerate case where the singular linear system reduces to a regular system,and to the existing results for singular systems in the absence of actuator saturation or when the disturbance is weak enough to not cause saturation.
