摘要
液压舵机是船舶运动控制系统的重要组成部分,但因非线性因素的影响,传统PID对其的控制效果不是很理想。本文根据"川崎"舵机的相关参数,建立了模糊PID模型,并通过Simulink对所建模型进行动态仿真,验证了模糊PID控制在非线性系统控制上的优越性。
The hydraulic steering gear is a significant part of the ship＇s transport control system. However, the result of traditional PID method is not so perfect due to the nonlinear factors. Consequently, the author establishes a fuzzy PID model according to the related parameters of ＂Chuanqi＂ steering gear and then simulates the fuzzy PID method via apply- ing the tool of Simulink, thus indicating that the fuzzy PID method is more suitable for the nonlinear system.
