摘要
针对混合代价函数,研究了参数不确定脉冲型混杂系统的保代价控制问题,给出了混杂状态反馈保代价控制律的设计方法,由此得到的控制律既能使系统闭环鲁棒渐近稳定,又可使系统的闭环混合代价指标在对象参数摄动的范围内不超过确定的上界.本文提出的控制律不仅包含连续时间动态,也包含离散事件动态,而且其离散事件动态行为不需要与被控系统的离散事件动态行为一致,因此设计时不要求被控系统的每个连续时间子系统都具有可控性.仿真结果表明所提设计方法是可行有效的.
For the uncertain impulsive hybrid dynamic systems （IHDSs） and the hybrid cost functions, the synthesis method of the guaranteed cost control laws via hybrid state feedback is developed. By the obtained control law, the perturbed IHDS can be asymptotically stabilized and the closed-loop hybrid cost is not greater than a specified upper limit for all admissible uncertainties. The control law considered here consists of the discrete event dynamics as well as the continuous time dynamics. The discrete event dynamics of the control law doesnot need to coincide exactly with the controlled hybrid system, so that the continuous time subsystems of the controlled hybrid system are not required to be controllable. The simulation result shows the effectiveness of the proposed approach.
