摘　　要：针对超临界机组动态特性复杂、变参数的运行方式、多变量的控制特点,提出二级过热汽温主调节器采用自抗扰控制器(ADRC),副调节器采用PID控制的设计方法,从而构成ADRC-PID方法来控制超临界主汽温。同时采用600MW超临界机组为被控对象进行试验研究。试验结果表明,用ADRC-PID控制主汽温对被控对象模型的不确定性和外部扰动变化具有较强的鲁棒性和适应性,控制系统具有优良的动态性能。Considering the complex dynamic property, parameter-variable operation and multi-variable control characteristics of supercritical unit, employing ADRC for the primary regulator of secondary superheated steam temperature and PID control for the subsidiary regulator to work out ADRC-PID method for the supercritical main steam temperature control was presented ; and a 600MW supercritical unit was taken as the controlled ob- ject in testing study. The results show that ADRC-PID method has strong robustness and adaptability for the controlled object with uncertainty and external disturbances.
