摘要
针对输入要求平稳的系统设备,提出了一种快速无超调预测控制新算法。该算法通过对输入增量引入柔化系数矩阵从而进行约束,防止了输入的剧烈变化;既达到了系统输入平稳的要求,又克服了传统控制律中求解逆矩阵的缺点,提高了系统响应的快速性。其次,控制算法中改善了传统广义预测控制算法的单一性,充分利用预测信息的补偿作用进行加权平均,很好地抑制了超调的出现。通过对水下航行器航向系统的仿真试验比较,试验结果验证了该算法的有效性。
Considering the requirement that the input signals of some industry system equipments have no sharp change, a kind of new control algorithm is presented. The input increase is constrainted by softing coefficient matrix to obtain smoothing input, and it is need not to calculat inverse matrix to increase responding speed of the system. The compensations of predictive information is fully used to form weighted average. It is a good way to restrain overshoot. The simulation results show the validity of the algorithm by comparative study for navigable system.
