摘要
常规PID控制器在一些复杂的控制系统中不能达到很好的控制效果,在此基础上引进了自抗扰控制器;自抗扰控制器不仅保留了PID控制器的优点,还在一定程度上改进了它的适用范围和控制品质;将PID控制器和自抗扰控制器分别应用于二阶非线性对象双容水箱中;并利用OPC技术实现Matlab与WinCC的通信,使自抗扰控制器的Matlab仿真与Wincc实时监控相结合,得到更精准的仿真效果;证明了自抗扰控制器既能实现无超调、无静差的控制,也易实现时滞对象的控制,有较好的适应性和鲁棒性,控制效果更好。
Conventional PID controller can＇t achieve good control in some complex control systems. On this basis, introduce the ADRC. ADRC not only retains the advantages of the PID controller. Also to some extent improve its scope and control of quality. PID controller and ADRC controller used in the second--order nonlinear object two--step water tank. And use OPC technology to achieve communicating Mat lab with Wincc. Combine real--time monitoring of ADRC in Matlab simulation and Winccandreach to more accurate simulation results. It proved ADRC controller can achieve no overshoot and no static error control, easily to implement the control of the time delay, and have good adaptability and robustness andcontrol is better.
