本伺服系統控制以PC-Based的方式，建構一即時全數位模糊自調式週期性重覆性位置控制系統，由實驗驗證本控制法則的正確性及可行性。 The objective of this paper is to utilizes fuzzy control which can self-tuning to build the intelligent fuzzy repetitive controller and apply to linear servo system. First, applicable motion characteristic curve is designed for the command of the linear servo motor. The proportional-integral (PI) controller and the phase lead compensator are designed to control the speed loop and the position loop for the linear servo drive system and improve the system to follow the command generated by the steady-state error.
In addition, in order to reduce the peak acceleration response and avoid the greater vibration caused by machinery operation, the linear servo system adjusts and utilizes its fuzzy logic according to different motion characteristic curve. The result will be applied to repetitive controller to improve the traditional fixed repetitive controller for the second-order low-pass filter value and makes better control of repetitive in different characteristic curves of the continuous cycle of the order to gain better motional response and reduce steady-state error.
Linear servo-drive system adopts PC-Base approach, using digital/analog interface and MATLAB/Simulink software to build a real-time position of repetitive motion control system, the experimental verification of this control law is indeed improving the system output response and reduce steady-state error and the peak acceleration response system.
