Design and implementation of robust Multirate Output feedback based Sliding Mode Controller for Induction Motors using FPGA

This paper demonstrates design of Multirate Output feedback(MROF) based Discrete-time Sliding Mode Controller(DSMC) for sensorless control of Induction Motor(IM) implemented using System Generator (SysGen). A multirate output technique is used to estimate the state variables of Induction Motor. For designing the observer and controller, a linearised model is used. The efficacy of the scheme is shown in the simulation result.
