- Abstract
- The basic function of any type of electric machine used in automotive powertrain is to propel the automobile in motor mode or to recharge the high-voltage battery in generator mode. The torque control of electric machine in motor and generator modes, using more efficient high-voltage battery, is a goal for the automotive industry. A good choice for Electric Vehicles (EVs), due to many advantages, is the Externally Excited Synchronous Machine (EESM). In this paper, a new optimal torque control algorithm for EESMs that aims at optimum torque control in the entire operating range based on a dual-rate sampling solution is presented. In order to test the developed algorithm a dynamic model of EESM is designed based on mathematical equations. The model is validated against the data obtained on a system testbench. The simulated results obtained with the proposed control strategy are compared with the ones obtained with the classical PID approach and the results show improved performances.
