Towards delta domain in predictive control-an application to the Space Crystal Furnace TITUS

A formulation of predictive control which uses a closely to the continuous time plant related delta description is given. Starting with the derivation of an end-point state weighted generalized predictive controller a polynomial controller representation is given and the theoretical value of the endpoint state weighting matrix is derived. The robustness with respect to additive plant/model mismatch is involved by /spl Hscr//sub /spl infin// analysis. The Space Crystal Furnace TITUS is modeled using strongly coupled symmetric composite systems. A final simulation underlines the improved accuracy of the temperature gradient.
