MODELING & SIMULATION OF VOLT/HZ SPEED CONTROL FOR INDUCTION MOTOR USING DSPACE PLATFORM

The rapid adoption of automation techniques in industry has increased the requirement for better process control. This has resulted in many new applications for AC variable speed drives (VSDs) to control the speed and torque of driven machinery. Variable speed drives (VSDs) are also used to meet particular starting and stopping requirements. The objective of this thesis is development of Voltage Source Inverter (VSI) using the dSPACE DS1104 DSP controller board for speed control of a phase induction motor. The board enables the linking of the MATLAB/Simulink model to the real time hardware. We have the feasibility of injecting real time analog and digital data into the MATLAB/Simulink model, process it to suit our model requirements, do the simulation, study the response in MATLAB/Control Desk and at the same time get real time analog and digital output from the DSP controller board.
