| Abstract |
In this paper is presented a precise analytic study of the influence of the mechanical acceleration on a classical PI torque controller in the DQ frame. We treate the case of a sinusoïdal space distribution synchronous servomotor fed by a PWM inverter. We show that acceleration creates lacks of torque, which make the speed regulation loop become slower. We shall show that including the compensation of the effects of Q in the PI torque controller permits us to avoid these lacks of torque. The robustness of the latter solution is tested. The above theorical study is validated by simulation and experimental results. |
