Design and analysis of linear parameter varying control for IPMSM using new European driving cycle

Electric traction motors are the most integral part of fully electric vehicles. Among all traction motors, based on high efficiency, power density, reliability, high torque-to-inertia ratio and control maturity, interior permanent magnet synchronous machine (IPMSM) has proved to be one of the most suitable choices. This paper compares and discusses the various state-of-the-art IPMSM control strategies based on key criteria such as robustness, performance, degree of complexity, and hardware implementation. In this paper, a robust gain scheduling LPV controller is designed for a nonlinear IPMSM in d–q reference frame taking into account the thermal effects. Linear Matrix Inequalities are used for synthesis conditions. The robust gain scheduling LPV adopts induced L₂ / L_∞ -norm performance specifications in LPV framework using stator resistance as scheduling time varying parameter. The LPV controller results are validated by comparing them to proportional integral derivative and linear quadratic integrator control techniques using the new European driving cycle.
