Application Research On The Method Of Structured Singular Value μ-Synthesis

Based on structured single value theory and ( up bound function, considering of the ( function's character, a ( value algorithm with simplex algorithm is proposed. The result indicates that this algorithm has higher calculation precision and needs shorter calculation time. A (-synthesis algorithm with simplex algorithm is developed from ( value calculation. Genetic algorithm is improved in some ways according to (-synthesis characters. Another (-synthesis algorithm is brought forward which bases on genetic algorithm. The result indicates that these two methods are simple, the controller has no high dimension and can be realized easily. At last, PID parameter optimizing method is introduced, which bases on the ( theory and Genetic Algorithm. Simulation results show that the control system designed according to this method has better robustness and anti-disturbance ability.
