    In this paper describes the speed output of DC motor. The DC motor is controlled by DC converter which is using the PLL controller. This proposed is designed and implemented the current output of the DC-DC chopper which fed to DC motor based on close-loop control. The close-loop control is obtained the small signal from the tachogenerator and encoder. The encoder is converted the small signal to similar PWM waveform feedback to PLL detector that is adjusted the PWM signal driven into DC chopper. In order control to applied high precision speed of DC motor.

    This paper presents multilevel regular-based binary multiplier switching method and parallel-full bridge inverter circuit for controlling speed of single-phase induction motor (SPIM). By constructing various types of 8 bit regular-based binary multiplier signal (RBM) modulated by single-phase multilevel signal, and then generating inverter output signal. This technique can improve the inverter output signal's performance, which demonstrates in term of reduction of total harmonic distortion (THD) and lower-order harmonic when applying to control the motor, resulting to improve the motor efficiency and performance.
