Conventional sliding mode control (SMO) utilizes a sign function and low-pass filter (LPF) to achieve sensorless of permanent magnet synchronous motor (PMSM). However, the introduction generates large number high harmonics, resulting in significant system output chattering, whereas addition LPF delays phase shifts. These degrade PMSM speed position estimation accuracy reduce performance. To imp...

Brushless dc motors are widely used in many industrial applications due to their high efficiency, high power density and ease of control. In this paper, sensorless direct torque control (DTC) of bldc motor is implemented using fuzzy logic. In actual DTC both torque and stator flux linkage is controlled. In the proposed system, the control of stator flux linkage is avoided because every commutat...

This paper presents the implementation of an adaptive supervisory sliding fuzzy cerebellar model articulation controller (FCMAC) in the speed sensorless vector control of an induction motor (IM) drive system. The proposed adaptive supervisory sliding FCMAC comprised a supervisory controller, integral sliding surface, and an adaptive FCMAC. The integral sliding surface was employed to eliminate ...

-This paper presents a nonlinear generalised predictive control scheme for a squirrel cage motor without speed sensor. Some of the difficulties faced are due to uncertainties in the parameters measurements, high cost to obtain state measurements in addition to the inherently non-linear behaviour. The control scheme presented is composed of a positioning predictive control and an open loop obser...

Nowadays, DC microgrids are preferred in the field of renewable energy. The autonomous aim to provide smooth power flow from renewables loads. While satisfying certain load profiles and sustaining as desired level, control converters is considerable. To ascend resilience microgrids, battery storage systems (BSSs) also used a backup unit for supplying uninterrupted power. main task BSSs compensa...
