摘要
提出一种新的多变量系统预测函数解耦控制(PFC)算法。该算法将多变量系统的PFC分散为若干单变量系统的PFC,使参数设计和算法求解大为简化。此外,利用该算法可得到一个解析的控制量计算方程,控制器参数均可离线计算,因此在线时算法简单、计算量小,可用于解决复杂的耦合控制问题。仿真结果表明了该算法的有效性和可行性。
A new predictive function decoupling control algorithm for MEMO systems is proposed. This algorithm can decompose the PFC of an MIMO system into PFCs of several SISO systems, thus efficiently simplifying the parameter design and reducing the calculation load significantly. In addition, an analytical linear control equation can be derived with the new PFC algorithm, and the controller coefficients can be calcukted off-line. Therefore, the obtained PFC algorithm is simple and can solve complicated coupling control problems. The simulation results show that the proposed algorithm is efficient and feasible.
