摘要：
In this paper, a discrete robust optimal control algorithm is proposed for the hydraulic elevator velocity control which is controlled by a variable frequency controller subjected to many uncertainties, such as unmodeling system dynamics, parameters variations and unknown external disturbances. The control algorithm consists of two parts, an optimal part and robust part. The optimal part is used to specify the characteristics of the whole system, and the robust part is used to over come the uncertainties of the system dynamics. The simulation and experimental results have shown that the proposed control algorithm is an effective optimum control with a satisfactory degree in accuracy for the hydraulic elevator velocity control system.
