Reliable control of regional stabilizability for linear systems
线性系统区域稳定的可靠控制

The reliable control design of regional stabilizability for linear systems is presented to avoid plant uncertainty and actuator faults.Based on the analysis of systems with continuous gain faults,the sufficient conditions for the existence of regional stabilizability reliable control synthesis were given,and then,the corresponding synthesis conditions for the reliable controllers were developed.The results were cast conveniently into a linear matrix inequality (LMI) framework,which could be solved numerically.The CH-47 helicopter flight control example was given,the computer simulation result illustrated the validity and effectiveness of the proposed methods.Furthermore,the necessity of the reliable design was addressed via the comparisons of the normal control and the reliable control.
