Abstract. Redundancy design scheme and control strategy of the energy management system for a stratospheric airship are proposed, which use the coordination control between the photovoltaic cell and lithium battery to maintain the DC bus voltage constant, so as to guarantee the stability of the motor load. The system can switch to corresponding working state according to different conditions through the analysis of the different control modes of unidirectional DC-DC and bidirectional DC-DC. The paper used MATLAB simulation, through increasing or decreasing the load at DC bus terminals and changing the input energy to detect the stability and reliability of the system. At the same time, the reconstruction ability of the system is tested by setting fault information for key nodes. The simulation results show that the proposed design scheme and control strategy not only maintains the stability of the bus voltage, but also makes fault isolated and achieves system reconstruction and effectively protects the storage battery.

This Paper mainly deals with the implementation of vector control technique using the brushless DC motor (BLDC). Generally tachogenerators, resolvers or incremental encoders are used to detect the speed. These sensors require careful mounting and alignment, and special attention is required with electrical noises. A speed sensor need additional space for mounting and maintenance and hence increases the cost and size of the drive system. These problems are eliminated by speed sensor less vector control by using Extended Kalman Filter and Back EMF method for position sensing. By using the EKF method and Back EMF method, the sensor less vector control of BLDC is implemented and its simulation using MATLAB/SIMULINK and hardware kit is implemented.

“…A Figura 3 apresenta a sequência de comutação ideal para um motor BLDC com FCEM trapezoidal. Em alguns estudos a posição do rotor é estimada baseado na detecção da passagem da tensão por zero, ZCP (do inglês Zero Crossing Point) [22]. As técnicas que usam o ZCP requerem um neutro de referência (real ou virtual), que é usado para comparar com a tensão dos terminais e determinar os instantes de comutação.…”
