摘要
非线性PID控制算法是一种利用非线性跟踪微分器和非线性组合方法对线性PID控制进行改进的新型控制策略,具有不依赖被控系统模型的特点。作者将这种控制算法用于机车防滑装置中,并基于SIMULINK对其进行仿真。结果显示,PID控制器简单,但在初始阶段的车轮锁死现象,会使车轮控制器的性能大打折扣;NPID控制器停车距离短,车轮转速响应快,参数易整定。
Non-linear PID control algorithm is a new type of control strategy, in which the non-linear tracking-differentiator and non-linear configuration are used to improve the performance of linear PID control, and it possesses the feature of not depending on the model of the controlled system. The authors applied this algorithm to an-t/-Skid system of locomotive and emulated it based on SIMULINK. Result declared： PID controller is simple, but the wheel is easy to be locked in initial stage. This condition can give a big discount to wheel controller; NPID controller is responded quickly, parked in short distance, and parameter in NPID controller is easy to adjust.
