Different Strategies of Sliding Mode Controller for speed control of Power factor corrected LUO Converter fed Switched Reluctance Motor [articol]

Abstract

Among the various special machines Switched Reluctance Motor is noted for high speed operation. This feature makes the drive application extent in various fields. Bridgeless Power Factor corrected LUO converter makes it possible to drive the Switched Reluctance Motor with the utility AC supply directly. This makes the machine suitable to be used for various domestic applications. Sliding mode controller is used for improving the speed regulation. The front end bridgeless Luo converter and the two legged drive system can be controlled to achieve the required speed. The duty cycle and modulation index are controlled in different configurations and make the system flexible to meet the various demands with reduced steady state error. The different speed control strategies or Modes are simulated in MATLAB SIMULINK and the performance parameters are compared.
