Design of the state predictive model following control system with time-delay

Dazhong WangShujing WuShigenori Okubo — 2009

International Journal of Applied Mathematics and Computer Science

Time-delay systems exist in many engineering fields such as transportation systems, communication systems, process engineering and, more recently, networked control systems. It usually results in unsatisfactory performance and is frequently a source of instability, so the control of time-delay systems is practically important. In this paper, a design of the state predictive model following control system (PMFCS) with time-delay is discussed. The bounded property of the internal states for the control...

Design of a model following control system for nonlinear descriptor system in discrete time

Shujing WuShigenori OkuboDazhong Wang — 2008

Kybernetika

A model following control system (MFCS) can output general signals following the desired ones. In this paper, a method of nonlinear MFCS will be extended to be a nonlinear descriptor system in discrete time. The nonlinear system studied in this paper has the property of norm constraint | | f ( v ( k ) ) | | α + β | | v ( k ) | | γ , where α 0 , β 0 , 0 γ < 1 . In this case, a new criterion is proposed to ensure the internal states be stable.

Model following control system with time delays

Design of model following control system (MFCS) for nonlinear system with time delays and disturbances is discussed. In this paper, the method of MFCS will be extended to nonlinear system with time delays. We set the nonlinear part f ( v ( t ) ) of the controlled object as | | f ( v ( t ) ) | | α + β | | v ( t ) | | γ , and show the bounded of internal states by separating the nonlinear part into γ 0 . Some preliminary numerical simulations are provided to demonstrate the effectiveness of the proposed method.
