For MIMO nonlinear differential-algebraic equations (DAE) subsystem, the Backstepping stabilization control method is studied and the results are applied to the decentralized control of power system. The concept of vector relative order for MIMO nonlinear DAE subsystem is put forward. If the vector relative order exists, then the subsystem can be transformed equivalently by a diffeomorphism and a...
This paper introduces the nonlinear speed control scheme for a permanent magnet synchronous motor (PMSM) drive. Based on the designed nonlinear sliding-mode control tracking a linear reference model, the adaptive backstepping control approach is utilized to derive the control scheme, which is robust to the mismatched parameter uncertainties and load torque disturbance. With the proposed control, the...
This paper investigates a nonlinear speed control scheme for a brushless DC motor (BLDC) drive. In order to achieve high performance speed tracking, an adaptive backstepping controller is designed to obtain the reference voltage for the pulse width modulation (PWM) control which does not require the traditional PI controller. To regulate the dynamics of the drive system, the proposed controller is...
