摘要

A nested high order sliding mode controller is proposed for speed control of a brushless direct current motor using an extended park transformation. Conventional park transformation applied to non sinusoidal back electromotive force motors results in non constant values in the(d, q)reference frame, a modified park transformation is used to obtain constant variables after transformation. Sliding mode control is robust in the presence of matched parametric variations and uncertain disturbances but unmatched variations have a negative effect in the system’s performance. A nested high order sliding mode scheme is presented to improve controller robustness to unmatched perturbations. Simulations are used to show the performance of the proposed controller with load torque and resistance variations.
