摘要
引入无穷时域的1-范数性能指标,通过施加新的终端等式约束确定出无穷时域性能指标的一个上界,将不可解的优化问题转化为可解的优化问题,从而提出保证连续时间广义预测控制闭环稳定性的准无穷时域方法.仿真例子证明了算法的有效性.
The closed-loop stability of the continuous-time generalized predictive control is considered, by using the infinite horizon control. The 1-norm cost function with infinite horizon is imported. By inflicting the new end-point equality constraints, an upper bound of the cost function with infinite horizon is given, and the unsolvable optimal problem can be transformed into a solvable optimal problem. Then the quasi-infinite horizon approach which can guarantee the closed loop stability of generalized predictive control is presented. Simulation result shows the validity of the proposed control.
