| Abstract |
Nonlinear decoupling and linearization techniques are applied to the control of a synchronous servomotor described by a nonlinear model expressed in the (d,q) frame. Proportional-Derivative controllers associated to the linearized and decoupled closed-loop system, assure asymptotic speed regulation while the direct current id, is maintained to zero. The addition of integrators together with the choice of a rectilinear reference trajectory for the speed, permit to improve the robustness of such a controller without exceeding predetermined constraints on the current iq. Simulation and experimentation results are presented. |
