Generalized predictive control algorithm with stability

针对广义预测控制中的输出量和控制增量波动较大而对系统产生冲击的难题,构造了一种新的预测控制算法。通过对广义预测控制算法中控制目标函数的控制增量加权系数进行在线动态修正,可有效地抑制输入量的波动,获得系统的稳定输出。仿真结果验证了该方法的可行性和有效性。

For solving the problem in practice engineering of the output and controlling increment fluctuation impact the system in generalized predictive control, an improved algorithm was proposed. The coefficient of controlling increment was corrected online by using predictive information for restrain the input fluctuation. The output stability was obtained. The feasibility and effectiveness of the algorithm are verified by simulations.
