Abstract
Non linearities effects can be reduced through the introduction of pulsewidth modulation, even for systems with simple and innacurate electrohydraulic servovalves. In this paper, a method of analysis of systems with PWM using two types of sampling, uniform and natural, is presented. Through the method of point transformation, mathematical models are established as explicit or implicit recurrent non-linear second order equations, and the corresponding double point local stability is studied for both cases of sampling.
