Adaptive Tracking for Discrete-Time Systems with the Unknown Control Directions

摘要：

This paper investigates indirect adaptive trackers for the general linear systems and extends the results of Ruan et al.1 to the general case of the linear discrete-time plants with the unknown control directions and model parameters. Make use of three different estimators respectively combine the modified certainty equivalence control law, we design the three adaptive tracacking systems which can overcome the difficulty of a loss of stability (or controllability) as the estimate of the plant gain is zero and analyze the stability of the designed adaptive tracking system. This analysis provides us with a conclusion of the boundedness properties of the resulting closed-loop systems. Two simulation ex- amples show that all signals of the resulting adaptive tracking systems are the globally bounded.
