H∞ control with local controller networks: application to induction motor

This paper present a nonlinear control structure known as a local controller network. The structure consists of a weighted combination of number of individual H_∞ 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. The design is carried out for the induction motor and simulation results are included.
