    ABSTRACT: This paper deals with the analysis and development of a permanent magnet brushless DC (PMBLDC) motor drive coupled to a pump load powered by solar photovoltaic (PV) array for water pumping system. A simple low-cost prototype controller has been designed and developed without current and position sensors which reduces drastically the overall cost of the drive system. This controller is used to test the dynamic behavior of the PMBLDC motor drive system. The mathematical model of the system is developed with a view to carry out a comparison between experimental and simulated response of the drive system. A simple filter circuit incorporated in between PV-array and an inverter to reduce ripples and to improve the performance of the PV-array. The necessary computer algorithm is developed to analyze the performance under different conditions of varying solar insolation for a pump load.

    ABSTRACT: This paper describes an experimental study carried out on a permanent magnet brushless DC (PMBLDC) motor drive coupled to a pump load powered by a photovoltaic (PV) array for water pumping system applications. A simple low-cost prototype controller has been designed and developed without current and position sensors which drastically reduces the overall cost of the motor drive system. This controller is used to test the dynamic behavior of the PMBLDC motor drive system. A mathematical model of the system is developed with a view to carrying out a comparison between the experimental and simulated response of the drive system. The necessary computer algorithm is developed to analyze the performance under different conditions of varying solar insolation for a pump load. The developed state-space equations are simulated to obtain the performance characteristics which are also verified by conducting a suitable experiment on the developed PV pumping system

    ABSTRACT: This paper deals with the performance analysis of the field oriented control (FOC) of permanent magnet synchronous motor (PMSM) drive with a PID (proportional plus integral plus derivative) in DC link voltage control and fuzzy PID for speed control in closed loop operation. A mathematical model of the PMSM drive has been developed by considering each accessories of the model to analyze both the steady state and transient performances of the PMSM drive system. The current controlled inverter feeding power to the PMSM motor is powered from a PWM current controlled converter. The advantages of the integrated PMSM drive are demonstrated. The PID voltage control takes care of the constant DC link voltage to feed the inverter. The fuzzy controller provides a better response to the drive system specially in the steady state condition. The state space model developed in terms of derivatives of winding currents, DC link voltage, supply currents, rotor speed, and rotor position are simulated to obtain the required information. The study also examines the effectiveness of the PMSM drive under steady state and transient conditions for different parameter variation

    ABSTRACT: The dynamic performance of a permanent magnet brushless DC (PMBDC) motor connected to photovoltaic (PV) array through an inverter is analyzed. The mathematical models of PV array, inverter/motor and controller are developed. The photovoltaic array is represented by an equivalent circuit whose parameters are computed using experimentally determined current-voltage (I–V) characteristics. The necessary computer algorithm is developed to analyze the performance under different conditions of the solar insolation for pump load. The study also examines the effectiveness of the drive system both for starting and DC link voltage fluctuations caused by varying solar insolation.

    ABSTRACT: Permanent magnet brushless dc (PMBLDC) motors are increasingly being used in a wide range of applications such as machine tools, robotics and high precision servo applications. A comprehensive analysis which includes modeling and simulation of PMBLDC motor drive is presented in this paper. A mathematical model of the drive is developed with a view to studying the transient response of current controlled voltage source inverter (VSI) fed PMBLDC motor. The drive system consists of discrete PID(Proportional, integral plus derivative) speed controller, the reference current generator, the position sensor, an inverter and the motor. Each part of the drive system is modeled separately and then integrated to study the dynamic behavior of the drive system. The study also examines the effectiveness of the drive system during starting, load perturbation, speed reversal and dc link voltage fluctuation.
