基于增量式方法的自抗扰控制无扰切换技术

Bumpless Transfer Techniques for Active Disturbance Rejection Control Based on Incremental Form

针对自抗扰控制在分散控制系统中的应用问题,研究了自抗扰控制的无扰切换方法。通过分析调节系统无扰切换原理,提出利用增量型线性自抗扰控制器实现无扰切换的方法。在电厂仿真机平台上编写了二阶线性自抗扰控制器模块,通过组态、运行验证了该方法可以实现自抗扰控制器的手/自动无扰切换、两种不同控制器之间的无扰切换。通过该方法可以将自抗扰控制应用到分散控制系统中,提高控制性能。

In order to apply the active disturbance rejection control(ADRC) to the distribute control system(DCS),this paper studies the methods for bumpless switch.By analyzing the principle of bumpless switch,this paper puts forward using the incremental type linear active disturbance rejection control(LADRC) to realize the bumoless switch.LADRC module is developed in a power plant simulator,through configuration and operation proved this method can realized man / auto and different controller bumpless switching.By using this method,ADRC can be easily used in DCS and improve control performance.
