| Summary: | 碩士 === 明志科技大學 === 機械工程系機械與機電工程碩士班 === 106 === Since a pneumatic actuating system has nonlinear uncertainty and time-varying characteristics, it is difficult to establish an accurate process model for designing a model-based controller to monitor the pneumatic actuating force. An intelligent control strategy with auto-tuning control gain for a pneumatic vibration isolation system is developed in this research. Since the neural network has strong learning ability and high degree of tolerance characteristics. It can be used for online adjustment the PI controller parameters. Time Delay Controller (TDC) can be used to predict the impact of time delays on the system. Hence, a neural network based self-tuning PI controller integrated with a time-delay controller is proposed in this research to control the diaphragm-type pneumatic vibration isolator. The experimental results show that the controller designed in this study can improve the time delay effect and obtain the obvious vibration isolation performance for controlling of pneumatic vibration isolation system.
