Summary: | 碩士 === 國防大學理工學院 === 兵器系統工程碩士班 === 97 === This work presents the applications of an intelligent fuzzy weighted input estimation controller to control the electrical and hydraulic servo system under the influence of unknown system variation and external interference maintain its high performance. This controller is composed of the adaptive fuzzy controller and the fuzzy weighted input estimation method. The adaptive fuzzy controller including the modification factor is mainly used to keep the system stable and prevent the system from vibrating. The robust fuzzy controller is the on-line estimation principle composed of the Kalman filter and the recursive least square estimator with the fuzzy weighting factor. By measuring the position and velocity of hydraulic strut and the pressure of hydraulic vessel, the displacement of valve shaft can be estimated. This method can be applied without using the stress sensors and can reduce the manufacturing cost. Besides, the system performance and adaptability can be enhanced. By simulating the parameters and comparing the simulation results with the ones using the adaptive fuzzy controller and the robust fuzzy controller, the method proposed in this paper can be verified to be capable of performing tracking rapidly and reducing the effects due to the noise under the influence of the environmental change. This method can resolve the control issue of the electrical and hydraulic servo within the weapon vehicle system by facilitating the readiness for firing and keeping the equipment balanced after the recoil force occurs.
