| 摘 要： | 由于多变量系统各变量之间往往存在严重耦合现象,在对系统进行对角解耦的基础上,设计了带约束输入的广义预测控制算法。该算法保证了系统输出有效跟踪设定值,并且充分考虑了输入信号及其增量均受约束的情况,使其均被控制在允许范围之内,同时避免了求解Diophantine方程,很大程度上减少了计算量。仿真结果表明该算法可以在很大程度上削弱变量之间的耦合程度,且具有良好的控制效果。

| Abstract: | Because MIMO system variables are often seriously coupled strongly, a generalized predictive control algorithm with constrained inputs is designed for multivariable system which is diagonally decoupled. The algorithm can ensure the outputs of the system track the set points well, and it takes into account all the constraints of the control signals and their increments. The strategy does not require calculating the Diophantine equations and needs only smaller computer memory.The simulation results show that it can significantly reduce the coupling of the variables, and has good control effect. |
