Continuous-time GPC with local controller networks: application to induction motor

This paper presents a nonlinear control structure known as a local controller network. The structure consists of a weighted combination of a number of individual continuous-time GPC controllers, each of which is valid locally in the state space of the plant. Local controller designs are based upon local models valid in operating regimes which correspond to N physical equilibrium points of the system. A stability analysis for the continuous-time local CGPC controller network with local state observer is given. The design is carried out for the induction motor, and simulation results are included
