Optimal process control law of torque for interior permanent magnet synchronous machine in pure electric vehicles

There are severe jerks while vehicle starts up sharply or accelerator steps, especially in AMT shifting. In order to guarantee ideal dynamic performance of torque response and ride comfort of vehicles, an optimal process control law of torque is proposed in this paper. The results of simulation and experiments demonstrate that the torque control law makes the shock intensity less and improves the ride comfort.
