Determination of the Optimal Parameters of the Pulse-width Modulated Voltage for Powering the Electromagnetic Vibration Drive
Goal. To determine the optimal parameters of various types of pulse-width modulated (PWM) voltage, which is used in the control systems of the electromagnetic vibration drive to create resonant vibrating machines and control the parameters of the working body of the vibrating machine in the resonant mode. Method. The work is based on the analysis of the spectrum of the main three forms of PWM signals in their low-frequency region, to which the oscillating mechanical system of vibrating machines responds.
