Chaos control of single time-scale brushless DC motor with sliding mode control method

摘要

In this paper, the sliding mode control (SMC) scheme ofsingle time-scale brushless DC motor (BLDCM) is investigated. The SMCmethod consists of 2 sections. To simplify the directive of thestability of the controlled single time-scale BLDCM in the slidingmode, first a special type of PI switching surface is adopted.Second, the SMC controller is obtained to guarantee the occurrence ofthe PI switching surface. The effectiveness of the theoreticalanalysis is evaluated by numerical simulations. Thus, the numericalresults are used to show the verification and trustworthiness of theproposed method.
