ABSTRACT This study investigates the performance of single-phase induction motor using microcontroller M68HC11E-9. The microcontroller senses the speed`s feedback signal and consequently provides the pulse width variation signal that sets the gate voltage of the chopper, which in turn provides the required voltage for the desired speed. A Buck chopper has been used to control the input voltage of a fully controlled single phase isolated gate bipolar transistor (IGBT) bridge inverter. PWM technique has been employed in this inverter to supply the motor with ac voltage. The proposed drive system is simulated using Matlab/Simulink. Its results were compared with the hardware experimental results. The simulation and laboratory results proved that the drive system can be used for the speed control of a single-phase induction motor with wide speed range.

    ABSTRACT: Over the last two decades, commercially available computer has become both increasingly powerful and increasingly affordable. This, in turn, has led to the emergence of highly sophisticated simulation software applications that not only enable high-fidelity simulation of dynamic systems and related controls, but also automatic code generation for implementation in industrial controllers. Today, electric drives, power electronic systems and their controls are getting more and more complex, and their use is widely increasing in all sectors: power systems, traction, hybrid vehicles, industrial and home electronics, automotive, naval and aerospace systems, etc. Advances in Microprocessors, Microcomputers, Microcontrollers such as DSP, FPGA, dSPACE etc. and Power Semiconductor devices have made tremendous impact on electric motor drives. Due to advancement of the software tools like MATLAB/SIMULINK with its Real Time Workshop (RTW) and Real Time Windows Target (RTWT), real time simulators are used extensively in many engineering fields, such as industry, education and research institutions. As consequences, inclusion of the real time simulation applications in modern engineering provides great help for the researcher and academicians. A case is made to present overview of the Real Time Simulations of Electrical Machine Drives possibility of including these techniques in modern engineering and practices. This paper will also discuss various real time simulation techniques such as Real Time Laboratory (RT Lab). Rapid Control Prototyping (RCP) and Hardware in the Loop (HIL) can be used in a modern engineering.
