Fault analysis with hybrid compensation for unbalanced distribution systems is proposed. The method employs the unbalanced three-phase model to analyse faults. Two matrices containing information of the topological characteristics of distribution networks were built along with the proposed hybrid-compensation method for analysis. Appropriate boundary conditions can be obtained for a fault to solve...
This paper proposes a sliding mode controller (SMC) design for a Brushless DC Motor (BLDCM) to achieve high-performance speed control. Based on Pulse-Width-Modulation (PWM) technique, a PWM-based controller in the inner current loop is first developed to perform a fast current control. A sliding mode speed controller is then designed in its outer control loop to enhance the speed control. Finally,...
