Abstract
In this Note, a nonlinear dynamic model of a PWM-driven pneumatic fast switching valve is presented. The electro-magnetic, mechanical and fluid subsystems of the valve are investigated, including their interactions. Unknown parameters are identified using direct search optimization and model validation is performed by comparing the simulated and measured current curves. In order to use this model in PWM control applications, a simplification strategy is also proposed and a static model is obtained between the duty cycle input and the moving average of the spool position. The simplified static model is validated again by experiments. To cite this article: M. Taghizadeh et al., C. R. Mecanique 337 (2009).Keywords
