摘要：

This article presents a useful analysis and synthesis technique for the design of multivariable feedback systems. Optimal robust decentralized controllers of diagonal dominant nominal model of parallel operating dc/dc converters using the structured singular value approach are designed. The proposed controllers are robust for reference signals or for disturbances. The robustness of feedback systems with designed controllers is tested and compared with a previously designed decentralized controller of the nominal model. Simulation results, in both frequency and time domain, demonstrate the superior performance of the designed decentralized controllers in disturbance rejection.
