PMBLDC motor (PMBLDCM) with non-linear controller usage in electric propulsion of electric vehicles to control rotor speed (RS) and torque (EMT)

In present days existing transportation vehicles replacing with electric vehicles (EVs) with the usage of PMBLDCM motor because of simplicity in design, rough usage, responding speed and its high efficiency. Due to usage of dynamic loads in electric vehicles with PMBLDCM motor controlling speed and electromagnetic torque were major problems. These problems along with other problems faced in electric propulsion system (EPS) of electric vehicles (EVs) can be solved with the usage of proposed non-linear controller (ANF-SMC) along with usage of PMBLDCM motor for speed regulation and fuzzy parameter tuning based on motor performance under variable speed conditions. Proposed controller designed by the usage of simulation software along fuzzy logic. To validate proposed non-linear control system performance results compared with other exhibiting one linear and three non-linear controllers. Simulation results proved that with various loaded conditions proposed system performs well in all aspects when compared to four existing controllers.
