摘　　要：静电除尘用大功率高频高压电源系统具有非线性、时变性、迟滞性等特点,需要一类数学模型要求低、自适应能力强的非线性控制方法;以自主研发的静电除尘用大功率高频高压电源为研究对象,基于现场实际电源系统试验结果,采用最小二乘法辨识系统的近似传递函数模型,最后设计了一种新颖的基于动态矩阵算法(DMC)的模型预测控制器,实现针对电源输出电压的控制;仿真结果表明,该算法具有稳定性好、自适应强等优点,并具有良好的控制效果。The dust movement by high-power high-frequency high-voltage power is characterized with nonlinear, time-varying, hystere- sis and so forth. Thus, it requires a nonlinear control algorithm which has better adaptive features and a low demand for mathematical mod- els. A high-power high-frequency high-voltage power, which is independently developed for electrostatic precipitator, is selected as the re- search object. Based on the field experiment results, parameters of the approximate transfer function are indentified by using least aquare method. A new Model Predictive Controller based on dynamic matrix control algorithm （DMC） is designed, realizing the control for the out- put voltage of power. Simulation results present that this algorithm has such advantages as good stability and strong self-adapting, with great control effects as a whole.
