Abstract :
A Super Twisting based step-by-step observer for a DC series motor is proposed. An observability analysis reveals that the system presents an observability singularity at zero current. To overcome this problem we propose the joint use of an estimator and an observer. Experimental results highlight the performances of the proposed observer/estimator in the context of a sensorless speed control.
