“…One motor working under the torque control mode is coupled to the test IPM motors to provide the required load. For the sake of comparison, apart from the offline-tested flux linkage values, the estimation results of a traditional magnetic flux estimation method in [16] are presented. Before illustrating the experimental results, it needs to be mentioned that first, the motor speed is 21 rad/s.…”

“…In this case, the identified flux linkage from those observers is not reliable, reducing the demagnetization fault diagnosis precision. Now, the main solution to this issue is to improve the machine model accuracy by using online resistance or inductance identification methods [16], but they seldom consider the inverse impact of PM demagnetization on the accuracy of resistance and inductance identification results. Hence, new flux linkage detection methods are highly required for the sake of accurate demagnetization detection.…”

This paper proposes a novel sliding mode (SM) disturbance observer-based technique to diagnose demagnetization fault of interior permanent magnet (IPM) motors with stator parameter mismatch impacts eliminated. First, the IPM motor model incorporating the disturbances caused by the PM demagnetization and stator parameter mismatch is established. Then, an SM disturbance observer is constructed to identify the overall disturbance caused by all parameters, with its stability discussed by using the Lyapunov function. Third, a current-analysis-based method is developed to extract the disturbance only caused by flux linkage mismatch from the overall disturbance. Third, the extracted disturbance is adopted to calculate the real flux linkage, achieving demagnetization fault judgment and demagnetization degree calculation. Finally, experiment is conducted on two IPM motors to validate the proposed flux linkage estimation and fault diagnosis methods.

“…One is to combine vector control or DTC to realize the regulation and control of motor current, speed and position. The other is the application of observers in PMSMs [78][79][80], including motor parameter identification [81][82][83][84][85], disturbance observation, and motor sensorless control [86][87][88][89]. This section will introduce the design principle of the sliding mode controller and its characteristics, along with summarizing some improved SMC.…”

With the increasingly widespread application of permanent magnet synchronous motors (PMSMs), it is required that PMSM can still maintain high efficiency and high reliability in complex environments. Due to the nonlinearity of PMSMs and the influence of external disturbances, its precise control is still a challenge. As a modern control scheme, sliding mode control can improve the control PMSM drive system. It has been successfully applied in the control of PMSMs and has become a hot spot in the motor drive system. This paper provides an overview of the current research status of sliding mode control strategies based on PMSMs and introduces the design of sliding mode controllers, as well as the development and application of high-order sliding mode control. The method of suppressing the chattering problem is summarized, and the deficiencies of it are put forward. Finally, the development trend of sliding mode control technology is discussed, and the future development direction of SMC for PMSM is prospected.
