Abstract
Paper presents experimental and simulation results with 4 kW induction motor drive. Experiments are done using hardware in the loop real time simulation which allows implementing of motor control directly from the personal computer. This technique enables to replace part of the system with computer model running software. Regulator model was simulated in Matlab/Simulink. PI and PID regulators were tested. Experimental and simulation results starting and loading the motor are elaborated. DOI: http://dx.doi.org/10.5755/j01.eee.19.2.3463
Highlights
Induction motors (IM) are the most common motors used in industrial motion control systems as well as in main powered home appliances
Lowcost, low maintenance and direct connection to an AC power source, reliability are the main advantages of AC induction motors
hardware in the loop (HIL) simulation allows for system and component test scenarios that would be impossible to implement
Summary
Induction motors (IM) are the most common motors used in industrial motion control systems as well as in main powered home appliances. Speed of an IM must be controlled in order to save energy and control technological process. The synchronous speed of the motor is proportional to supply frequency and is inversely proportional to the number of stator poles. For control of induction motor speed usually frequency converters are used. Hardware in the loop (HIL) control technology for the investigation of 4 kW IM is used. HIL simulation allows for system and component test scenarios that would be impossible to implement. The HIL technology is used to control the rotation speed of IM. This method allows controlling of IM directly from personal computer. The performance time domain characteristics of investigation system with HIL simulation in Matlab is presented.
