摘要： 在分析PID算法和广义预测控制算法的基础上，将广义预测控制算法的性能指标构造成PID形式，并推导出改进的PID型广义预测控制算法(PIDGPC)。通过在发电厂的过热蒸汽温度串级控制系统中的仿真，在时域内分析PIDGPC算法控制器的参数选择对控制性能的影响，说明PIDGPC算法比基本广义预测控制算法具有更好的控制性能，具有较好的应用前景。

Abstract: Based on the analysis of PID algorithm and Generalized Predictive Control(GPC) algorithm, the performance index of GPC algorithm is restructured as PID form. The derivation of PID-type Generalized Predictive Control(PIDGPC) algorithm is given. The influence of PIDGPC controller parameter tuning on system performance is analyzed in time domain with simulations in cascade control system for superheated steam temperature in thermal power plant. Compared with conventional GPC algorithm, PIDGPC algorithm has better control performance, and there are good prospects for engineering application.
