“…SMC is a popular nonlinear method for PMSM control [ 11 , 12 , 13 , 14 , 15 ]. As the sliding mode can be designed and independent of the object parameters and disturbances, SMC has the advantages of quick response, insensitivity to parameter changes and disturbances, no on-line identification, and simple physical realization.…”

Torque ripples caused by cogging torque, flux harmonics, and current measurement error seriously restrict the application of a permanent magnet synchronous motor (PMSM), which has been paid more and more attention for the use in inertial stabilized platforms. Sliding mode control (SMC), in parallel with the classical proportional integral (PI) controller, has a high advantage to suppress the torque ripples as its invariance to disturbances. However, since the high switching gain tends to cause chattering and it requires derivative of signals which is not readily obtainable without an acceleration signal sensor. Therefore, this paper proposes a robust SMC scheme based on a rapid nonlinear tracking differentiator (NTD) and a disturbance observer (DOB) to further improve the performance of the SMC. The NTD is employed to providing the derivative of the signal, and the DOB is utilized to estimate the system lumped disturbances, including parameter variations and external disturbances. On the one hand, DOB can compensate the robust SMC speed controller, it can reduce the chattering of SMC on the other hand. Experiments were carried out on an ARM and DSP-based platform. The obtained experimental results demonstrate that the robust SMC scheme has an improved performance with inertia stability and it exhibits a satisfactory anti-disturbance performance compared to the traditional methods.

“…The idea of MRAS 2 Mathematical Problems in Engineering is to build a reference model of the PMSM system without containing unknown parameters and to obtain the difference between the reference model outputs and actual system outputs. Next, an appropriate adaptive law will be designed to adjust parameters of reference model in real time according to the difference [10]. But the accuracy of this method depends on the designed reference model, which may prohibit the convergence of the system.…”

This paper presents a sensorless speed control strategy for a permanent-magnet synchronous motor (PMSM) based on an adaptive nonlinear extended state observer (ANLESO). In this paper, an extended state observer (ESO), which takes back-EMF (back electromotive force) as an extended state, is used to estimate the rotor position and the rotor speed because of its simpler structure and higher accuracy. Both linear ESO (LESO) and nonlinear ESO (NLESO) are considered to estimate the back-EMF of PMSM, and NLESO is finally implemented due to its obvious advantage in convergence. The convergence characteristics of the estimation error of the observer are analyzed by the Lyapunov theory. In order to take both stability and steady-state error into consideration, an adaptive NLESO is proposed, which adaptively adjusts the parameters of NLESO to a compromised value. The performance of the proposed method was demonstrated by simulations and experiments.

“…In document [1], a robust control for PMSM based on load prediction is proposed. A model reference adaptive control to overcome the influence of load turbulence is developed in literature [2]. In literature [3], a discrete-time reaching law control combined with internal-model control to restrain speed is implemented.…”

Permanent-Magnet Synchronous Motor (PMSM) is a multivariable nonlinear system with strong coupling. In this paper, a new decoupling method is proposed for a double closed-loop system with the speed feedback in external loop and the current feedback in internal loop, in which the sampling time of external speed loop is much longer than that of internal current loop. When the calculation of the current loop is carried out using Sliding Mode Control (SMC), the speed in external loop is made as a constant.In this case, the SMC controller is a multi-input multi-output system with variable coefficients. Compared with conventional PID control, the proposed approach demonstrates strong robustness against disturbance and has a rapid response.
