摘　　要：将无穷时域的性能指标引入连续时间的广义预测控制,通过施加新的终端等式约束,把包含无穷时域性能指标的优化问题转化成可解的二次规划问题.利用后退时域性能指标的单调性,给出了保证连续时间广义预测控制闭环稳定性的条件.仿真例子验证了该算法的有效性.The cost function with infinite horizon is imported into the continuous-time generalized predictive control. By importing the new end-point equality constraints, the optimal problem which has a cost function with infinite horizon can be transformed into a solvable quadric programming problem. The condition for guaranting the stability of the closed-loop system of continuous-time generalized predictive control is given according to the monotonicity of the receding-horizon cost. Simulation result shows the effectiveness of the algorithm.
