The Study of Predictive Quadratic Stability of Nonparameter Control System
非参数控制系统的预测二次稳定性研究

The concept of predictive quadratic stability (PQS) is proposed for the first time. The sufficient conditions of the PQS of nonparameter plant with bounded uncertainty are proved theoretically in this paper. LMIs is used to describe these conditions. At the same time, the PQS sufficient conditions of plant constrained by I/O saturation is presented. Moreover, the PQS means the global robust stability of nonparameter plant. After all,the robust stability problem of predictive control system which is easy to model and convenient to realize is solved theoretically.
