摘要
Several different control algorithms for high-order inertial system were researched recently in China. Since different algorithms have similar effects, the consistency of these algorithms was first proposed in this paper in the view of control principle. The superheated steam temperature system of a 600 MW unit was taken as an object. The characteristics of time domain and frequency domain, spectrum of local disturbance signals, robustness under model perturbation, and the real actuator output were analyzed and discussed. The conclusion is that the different algorithms applied in practice do have consistency; these algorithms have intrinsic deficiency, which is derived from the structure of the algorithms themselves. Finally it has carried on prospect for future research and some problems meriting our attention. © 2010 IEEE.
