摘要
建立2135型柴油机调速器的非线性模型,设计一种滑模控制器,以实现对单输入非线性柴油机调速系统的控制,并用MatLab/Simulink仿真,体现出滑模变结构控制对非线性系统进行控制的动态、静态品质优良,鲁棒性好的特点,解决传统PID控制超调量大、调节时间长的问题。针对滑模变结构控制器容易产生抖振的问题,设计了自适应离散滑模控制器,取得较好的仿真结果。
In order to control speed of the one inputting nonlinear engine, the nonlinear model of the 2135 engine governor the sliding mode variable structure controller is designed in the paper. Through MATLAB/ Simulink, it is proven that the sliding mode variable structure control（VSC） is able to response quickly, invariant against systemic parameters and external disturbance, and able to keep the system stable, obtain strong robustness. This paper solves the problem that for the conventional PIE） controller, peak overshoot is too great, settling and rise times are too long. Finally, in order to solve the problem of shaking, an adaptive sliding mode variable structure controller was designed whose simulation result is better.
