Optimal static output feedback stabilization of singularly perturbed discretetime systems
Control System Laboratory, Department of Electrical Engineering, National Cheng Kung University Tainan, Taiwan 70101, Republic of China
This paper addresses the static outputfeedback stabilization problem for a singularly perturbed discretetime system. Three issues for this kind of problem are investigated in detail. The optimization of the nominal system with a stable fast model is examined first. Secondly, stabilization with gain spillover suppression is developed, and its associated linearquadratic synthesis procedures are given. Finally, the nearoptimal outputfeedback regulation problem is explored; both nearoptimal gain, and nearoptimal performance are zerothorder approximations to the optimal values. A steam power systemo is exploited to illustrate the proposed schemes.
