Speed Controller design via sliding mode control approach of induction motor with different sliding surface and with different speed control approaches of Induction motor are reviewed and presented. DSP based Sliding mode controller implementation approaches are also discussed. Sliding Mode control approach based designed controller provides robust performance with parameter variations and load variations. Different sliding surfaces and control laws based on equivalent control and switching control are reviewed and presented. Conventional design of controller block, total sliding mode control, observer based sliding mode design methods are presented and discussed. This survey paper is supported by the SIMULINK-MATLAB Simulation with one of the sliding surface and equivalent control based Sliding mode controller and Conventional P-I controller for the performance analysis of speed controller for d-q Model of Induction Motor.

This paper presents real time implementation of DSP based Sine PWM control algorithm for 3 phase 4-leg IGBT voltage source inverter. This method is useful to control the speed of Voltage source Inverter fed Induction motor drive. The pulses were generated using DSP controller through MATLAB Simulink-Code Composer Studio environment and that triggers the inverter. Results of input and output of the inverter were captured using Digital Storage Oscilloscope. Simulation study was carried out using PSpice and results verified.

This paper presents real time hardware implementation of DSP based 180 degree control algorithm and MATLAB SIMULINK based software Implementation for 3-phase 4-leg IGBT based voltage source inverter. Triggering pulses generated using Texas Instruments TMS 320F28335 DSP controller and that triggers the 6 IGBTs of Voltage source inverter. Results of pulse generated using DSP and output of the Voltage source inverter were captured using Digital Storage Oscilloscope. FFT analysis for output signal of software and hardware implementation presented with the analysis.
