Fractional calculus is a generalization of the integration and differentiation to the fractional (non-integer) order. In this paper, we devised a fractional-order periodic adaptive learning compensation (FO-PALC) method for cogging effect minimization for permanent magnetic synchronous motors (PMSM) position and velocity servo system. Cogging effect is a major disadvantage of PMSM. In fact, the cogging...
Cogging effect is a serious disadvantage of the permanent magnetic synchronous motor (PMSM), and cogging force is a position-dependent periodic disturbance. In our previous work [1], a dual high-order periodic adaptive learning compensation (DHO-PALC) method for state-dependent periodic disturbance was presented, where the long term stability issue was not addressed. Due to the impact of the high...
In this paper, a simulation model of PMSM position servo system is presented briefly first, we then propose a high order periodic adaptive learning compensation (HO-PALC) method for cogging effect on PMSM position and velocity servo tasks. The cogging force is considered as a position-dependent disturbance that is periodic. The key idea of the implemented cogging disturbance compensation method is...
This paper presented a detailed authentic simulation model of a permanent magnet synchronous motor control system based on the SimPowerSystems toolbox in Simulink library. We then focus on the periodic adaptive learning compensation (PALC) for cogging effect on PMSM position and velocity servo tasks. The cogging force is considered as a position-dependent disturbance that is periodic and not necessarily...
