Robust Tracking Control for Linear Systems Containing Time-Varying Uncertainties
含时变不确定性线性系统的鲁棒跟踪控制

This paper is concerned with the problem of designing robust tracking controllers for the linear systems with time-varying uncertainties. Using Riccati equations, we derive a linear control law which produces robust tracking of dynamic inputs.In the matched system, the tracking, error bound can be made arbitrarily small, and then a satisfactory practical tracking is achieved. I the mismatched system, with some other conditions holding, the tracking error can be made bounded.
