Passivity based control of DC motor in sensorless configuration is proposed in this paper. Exact tracking error dynamics passive output feedback control is used for stabilizing the speed of Buck converter fed DC motor under various load torques such as constant type, fan type, propeller type, and unknown load torques. Under load conditions, sensorless online algebraic approach is proposed, and ...

Permanent magnet brushless DC (PMBLDC) motors are the latest choice of researchers due to their high efficiency, silent operation, compact size, high reliability and low maintenance requirements. These motors are preferred for numerous applications; however, most of them require sensorless control of these motors. The operation of PMBLDC motors requires rotor-position sensing for controlling th...

1 This work is sponsored by DARPA under Fort Huachuca Contract No. DABT-63-92-C-0052 Abstract: In this paper we will introduce the use of dynamic vector force fields as a means of moving parts between work cells on an Intelligent Motion Surface (IMS). The idea is to put a force field around a part and move the force field in a continuous or discrete way, dragging the part along with the field. ...

This paper proposes grid voltage sensorless model predictive control for a single-phase T-type rectifier with an active power decoupling circuit. The proposed technique is based on reference adaptive system (MRAS) and tested under distorted conditions. study also examines the relationship among ripple energy, dc-link capacitor, circuit capacitor. developed to ensure following objectives; (1) es...
