| Abstract |
We proposed a mehod based on technological criterion approach and frequency modelization for the design of a DC permanent magnet actuator inner current loop, which is driven by a pulse width modulated (PWM) amplifier. This is an accurate method which takes into account supply amplifier-motor dynamics and saturation. It brings a model which includes the input control voltage sampling effect with a digital controller. We introduced the notion of 'carrier wave', then advantages and limits of two types of carrier and input control waves are discussed with results for a continuous-time control system and with a digital controller. The main results of the « frequency PWM modeliz.ation » (5) are recalled. The model is tested through simulations and experiments with a closed loop system. |
