积分分离与变速积分PID算法的比较研究

Research on the comparation between PID algorithm of integral separation and PID algorithm of alteration in rate

积分分离和变速积分两种PID控制算法在控制方法上类似,容易引起混淆。对两种算法的适用环境和算法实现进行了比较,基于MATLAB环境采用仿真分析的方法,对两种算法应用具体对象的控制效果进行了分析比较,得到了有用的结论。

There are two similar PID algorithms, one is PID algorithm of integral separation ,the othe is PID algorithm of alteration in rate , theyte easily mixed. A particular comparation was made on the two algorithms＇application condition and realization way, according to the digital simulation of control system based on MATLAB, their control effects are calculated and analysed, some useful conclusions are received.
