Item Position control of Interior Permanent Magnet Synchronous Motor using Adaptive Backstepping technique(IEEE Computer Society, 2013) Prashanth, K.V.; Girisha Navada, H.This paper mainly presents a novel method for developing control algorithm for position control of Interior Permanent Magnet Synchronous Motor (IPMSM) for servo drive applications. Adaptive Backstepping technique is used to build the control laws. The control technique incorporates the uncertainties occurring from variable side as well as from the parameter side. Stability of the controller is verified using Lyapunov Stability Theory and it found to be asymptotically stable. Simulation of the proposed control technique has been carried out using MATLAB/Simulink software. © 2013 IEEE.Item Parameter estimation of PMSM using adaptive backstepping technique(IEEE Computer Society, 2014) Prashanth, K.V.; Girisha Navada, H.Estimation of unknown parameters in non-linear systems is a very crucial part in the adaptive control. In this paper an adaptive backstepping procedure is discussed for the estimation of parameters of Permanent Magnet Synchronous Motor drive(PMSM) viz. variation of d-q axis inductances and load torque. Also, a non-linear control scheme using adaptive backstepping technique for speed control of PMSM drive is presented. Stability of the system is ensured by Lyapunov stability theory. Simulation of speed controlled PMSM drive along with the control technique is carried out using MATLAB/Simulink software. The system is simulated for different operating conditions like variation in load and reference speed. © 2014 IEEE.
