【 摘 要 】

In view of the demand in the operation process of lock gate as "slow start-fast run-slow stop", our study introduced the variable frequency control technology and established the opening and closing machine control system model. We conducted the closed-loop control simulation based on fuzzy PID to effectively suppress or eliminate the influence of error. Thus, the optimal control algorithm and strategy are obtained, and the precise control of the opening and closing process of the miter gate is realized.
