Abstract:
— This paper presents the solution of the nonlinear
optimal control problem of three-phase induction motor (IM).
A third order nonlinear model described in arbitrary rotating
frame of induction motor is used in this paper along with
a quadratic performance index. The problem is solved using
the quasilineraization approach which converts the nonlinear
optimal control problem into sequence of linear quadratic
optimal control problems. The optimal trajectories of fluxes,
speed, currents, and torque that represent the model states
and controls of IM are presented in this paper.
