提出了一种滑模等式约束的广义预测控制方法.该方法将广义预测控制与离散滑模控制结合起来用于具有大惯性、大时滞、时变和非线性的热力站换热机组的供水温度控制系统中,并采用柔化输入信号的方法,可避免广义预测控制算法中的矩阵求逆,有效缩短了预测时域,减小计算量.最后给出了稳定性分析并通过仿真验证了该方法的有效性.

Generalized predictive control with sliding model constraints for time-delay systems

A kind of generalized predictive control with sliding-model constraints for time-delay systems was proposed. This algorithm combine generalized predictive control with sliding-model control, which was applied to the heat-exchange unit in the thermal station and the water supply temperature control system whose dynamic characteristics of large inertia, large pure delay,time-varying, nonlinear, and add the soft coefficient to input signal, in which the inverse matrix does not require calculation. The method reduces the predictive and at last the stability of GPC system is analyzed. Meanwhile the simulated results have shows the effectiveness of this algorithm.
