Abstract :
This paper shows the design and the stability analysis of a Variable Structure Adaptive Pole Placement Controller (VS-APPC) for first order plants, both for regulation and tracking. The VS-APPC was proposed in previous papers and it provides a fast and non-oscillatory transient. Besides, it suggests robustness to parameter uncertainties and disturbances, by using switching adaptive laws for the plant parameters, instead of the traditional integral ones, as the gradient method. Additionally, simulations results are shown.
