Abstract
This paper deals with the speed control of a DC servomotor characterised by relevant nonlinear friction. A feedforward compensation of the nonlinear friction is proposed and implemented by using a dynamic model of friction. The error in the controlled system is eliminated by a suitable feedback controller. Experimental results have shown the robustness against variations of the nonlinear friction. The signal processing is performed by a DSP32C digital signal processor
