针对PID对大滞后大惯性系统的控制效果不佳、参数整定复杂等方面的不足,将预测控制应用到时滞控制系统当中,并在MATLAB环境下进行仿真。以算例证明预测控制应用于时滞控制系统中,比单纯的PID控制具有更良好的鲁棒性和抗干扰性,不但调节速度更快,参数整定方法更简单,而且还不依赖于对象模型的参数,非常适用于工业过程控制。 Aiming at the shortcomings of PID, such as poor control effect on large lag and large inertia system and complex parameter setting, the predictive control is applied to the time-delay control system and simulated in MATLAB environment. An example is given to demonstrate that predictive control is applied to a time-delay control system, which has better robustness and anti-interference than pure PID control. It not only has faster regulation but also has a simple parameter tuning method and does not depend on the object model The parameters, ideal for industrial process control.
