研究了混合摄动模式下反馈系统鲁棒稳定的摄动界。系统的正向通道为带有参数不确定性的线性系统 ,其不确定性为区间摄动模式 ,反馈通道为由积分二次约束给出的输入输出不确定性加以描述。用Minkowski泛函给出区间摄动模式下的摄动界的定义 ,并给出参数空间中混合摄动模式下系统摄动界的估计式。在一些典型摄动模式下给出这类混合摄动系统的摄动界的有限检验结果。
The perturbed bounds of the feedback system under mixed perturbation mode are studied. The forward channel of the system is a linear system with parameter uncertainty, the uncertainty is the interval perturbation mode, and the feedback channel is described as the input and output uncertainty given by the integral quadratic constraint. The definition of the perturbation boundary in the interval perturbation mode is given by the Minkowski functional and the estimate of the system perturbation boundary in the mixed perturbation mode is given. In some typical perturbation modes, the finite test results of the perturbation boundary of this kind of hybrid perturbation system are given.
