This paper presents the comparison power quality of the voltage source inverter type a space vector pulse width modulation (SVPWM) and sinusoidal pulse width modulation (SPWM) technique for adjust speed of the induction motor. All the drives are implemented on real-time Simulink model of three phase variable magnitude of voltage and variable frequency type are used the drive voltage source inverter system. This scheme leads to be able to adjust the speed of the motor by control the frequency and amplitude of the model. The ratio of input stator voltage to frequency should be kept constant. The overall control system is implemented on dSPACE DSP DS1104 controller board. The power quality of voltage source inverter are measured and compared to supply the 120 watt induction motor full load condition.

This paper presents design and implements the two degree of freedom (T-DOF) technique to design using Matlab/simulink for a reactive power and voltage control system of the synchronous generator. The proposed controller will be a Proportional Integral Derivative(PID) controller. The T-DOF PID controller design by root locus technique is also introduced to the system for regulates and tracking terminal voltage response. The overall control system is implemented on dSPACE DSP DS1104 controller board. This scheme leads to be able to adjust the output voltage of the generator by control the input voltage of exciter. The experimental results in testing the 300 watt generator system from no load condition to rated condition show the effectiveness of the proposed control scheme. It is found that the output phase voltage can be controlled to be constant in the operating range of 80-110 volt of a resistive, inductive and capacitive load.

This paper presents design and implement a V/F control speed of induction motor. This scheme leads to be able to adjust the speed of the motor by control the frequency and amplitude of the stator voltage, the ratio of stator voltage to frequency should be kept constant, which is known as V/F or scalar control. The PI controller is applied to speed signal model of the inverter and is then downloaded to dSPACE through Simulink. The experimental results are analyzed and compared simulation in testing the 0.22 kW induction motor from no-load condition to rated condition, it's found that the motor speed to be constant when the load varies, as shown the effectiveness of the proposed control scheme.
