This paper presents a single ended primary inductor converter (SEPIC) as a power factor correction (PFC) converter which is operated in voltage control mode for the speed control of a permanent magnet brushless DC motor (PMBLDCM) driven air-conditioner (Air-Con). The proposed converter combines the PFC and DC link voltage control in single stage and uses only one controller. The PFC controller uses...
This paper presents a novel PID self regulating tri loop controller for a hybrid PV-FC-Diesel-Battery powered all-wheel drive electric vehicle using four Permanent Magnet DC (PMDC) motors, which are modeled to include existing nonlinearities in motor plus load inertia (J) and viscous friction (B). A Tri Loop dynamic error driven scheme is based on Multi Objective Particle Swarm Optimization MOPSO...
This paper presents a voltage controlled scheme for brushless DC (BLDC) motor drives. The scheme combines both the low speed PWM control and the high speed phase advance commutation to obtain an extended speed range drive feature. In addition, the proposed scheme does not have a current control loop. Hence, no current sensor is needed in the drive. To satisfy the required over load protection demand,...
This paper presents a novel scheme for the speed/position control of permanent-magnet (PM) DC motor drives. A cascade-control scheme, based on multiple instances of a second-order sliding-mode-control (2-SMC) algorithm, is suggested, which provides accurate tracking performance under large uncertainty about the motor and load parameters. The overall control scheme is composed of three main blocks:...
