Digital control via interval analysis

This paper deals with the problem of trajectory tracking in parametric unce rtain systems. A new interval-based digital controller is presented to impr ove the dynamic performance of the system. Based on the predictive control theory, controller design is made via interval analysis,by taking into acco unt of the parameter uncertainty in the model. It is shown by a simple nume rical example that the developed controller exhibits an excellent robust pe rformance in the convergence of the tracking error and the stabilization of the controlled process.
