Abstract :
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.
