Summary
In the study, we analyse the experimental implementation of the act-and-wait control concept used for the purpose of digital position control. The initial model and simulation demonstrates the relevance of the control concept, which results are validated by experiments on a linear actuator. To get a better explanation of the measurement results, the model of the controlled system is improved. The effects of back electromotive force and the inductance is included into the motor model. The effect of the damping from dry friction is considered. Moreover, the limiting factors of the electric circuit are included on the voltage and current, which serves as a nonlinear saturation effect on the control. The significance of the different effect are analysed and compared to the measurement results.
