摘要:
This paper is concerned with the design and implementation of a position adaptive nonlinear zero-dynamic tracking controller (ANZTC) for a three phase squirrel-cage induction motor. A linear extended state observer (LESO) is proposed to estimate a part of the system dynamics, but also to estimate the internal disturbances generated by parameter variation due to changes in the motor temperature. The estimated values by LESO observer are adapted to a nonlinear zero-dynamic controller in order to improve the trajectory tracking performance. Experimental results of the proposed controller and a classical field oriented control are compared. Both control techniques were implemented in a dSPACE (R) 1104 equipment.
