A New Synergetic Scheme Control of Electric Vehicle Propelled by Six-phase Permanent Magnet Synchronous Motor

Electric Vehicles (EVs) are a promising al- ternative to conventional vehicles powered by internal combustion motors, offering the possibility of reduc- ing CO2, pollutants, and noise emissions. As known, the control of such an electric vehicle takes into ac- count several phenomena governing its behavior, which is a complicated problem because of the non-linearities, unmeasured disturbance, and parameters uncertainty of this system. This problem is one of the important challenges facing controller designers. Various control techniques have been proposed to enhance Ev’s perfor- mance. On this basis, in this research, a new synergetic scheme of electric vehicles propelled by Six-Phase Per- manent Magnet Synchronous Motor (PMSMs) is de- veloped. The synthesis of the proposed Synergetic Con- troller (SC) is based on the selection of four-manifolds of stator current of PMSMs. The SC provides fast response, asymptotic stability of the closed-loop sys- tem in wide range operating condition, and decrease the size of modeled system. Also, the principal fea- ture of SC is that it supports parameters variation. Furthermore, to illustrate the improvements and the performances of the proposed controller, a compari- son study between various nonlinear controllers such as Integral Action in Sliding Mode (ISMC), Super Twist- ing Sliding Mode (STSM), using a dynamic model of the lightweight vehicle under New European Driv- ing Cycle (NEDC) was done. The obtained simula- tion results under several operating conditions show the efficiency and superiority of the proposed control compared with nonlinear controllers; also, it demon- strates the feasibility of the proposed control approach for real system
