Output predictions of generalized predictive control (GPC) are obtained by solving the Diophantine Equation based on the present model parameters. Therefore, exact value of prediction would not calculate for time-varying system changing model parameter fast.
In this paper, we shows output predictor and control law of GPC for time-varying system suggested by O.P. Palsson et al. (1993) without giving a practical value to model dimension and costing horizon for simplify. Then, we investigate properties of GPC for time-varying system and compare response with conventional GPC. Responses of the closed loop system for various reference values and effect of filter removing offset are verified.
