In this study, a robust H2 suboptimal control method is proposed for an electro-hydraulic system with variable supply pressure. The H2 suboptimal controller is designed to minimize the sum of a quadratic performance criterion and the H2 norm of the closed-loop transfer function from the white noise disturbance to the system state space variables. The genetic algorithm is used to select the weighting matrices of the quadratic performance criterion. In order to improve the robust performance, parameter uncertainties of the electro-hydraulic system are considered in the process of genetic search. Simulation results demonstrate the effectiveness of the proposed approach. |
