This paper presents an improved position-sensorless field-oriented control strategy for a surface-mount permanent magnet synchronous motor (PMSM). In this algorithm, a high-pass filter (HPF) has been applied to the rotor flux estimation to solve the DC drift or offset problem caused by the integration part. The rotor position and speed signal extraction is achieved by mean of a phase-lock loop (PLL)...
The global optimal control problem with free system terminal states is proposed for the hybrid impulsive and switching systems (HISS). Towards the problem mentioned above, the necessary condition of the above problem, the HISS' minimum principle, is given. In the process of proving the above theorem, the Ekeland's variational principle and the matrix cost functional formulation are utilized. Based...
Towards a special class of hybrid systems, the hybrid systems with impulses and switches, a global optimal control problem with free system terminal states is proposed in this paper. Based on this problem, the necessary condition is studied, and then the HISS' minimum principle is obtained. In the proof of the above theorem, the general variational methods and matrix cost functional formulations are...
