The brushless double-fed hybrid poles permanent generator is a new-style HESM. The basic principle and structure of the machine are introduced first. The paper presents the voltage regulator of this generator, which is composed of TCR. In the paper, the simulation models of the machine and voltage regulator are established according to the MATLAB. Finally, the simulation results are provided to demonstrate...
This paper deals with the modelling and the control of a five-phase machine using a tooth-concentrated winding technology. It is shown that the control of the torque can be easily performed in a generalized dq reference frame, and that with this control the motor can still operate when the feeding of one phase is lost. This makes the motor under study and its control architecture a good candidate...
This paper presents a design method of Hinfin controller of the synchronous generator used in aircraft power supply system. A linear system model of generator is provided, and an approach of solving Hinfin control was offered. In order to manifest the control effect of Hinfin controller, a generator with traditionary PSS excitation controller was offered. The simulation results show that the Hinfin...
The brushless doubly-fed machine (BDFM) has prospect application in the wind energy conversion system (WECS) for its abilities of speed regulation and variable-speed constant-frequency. The decoupled control of the active and reactive power is crucial to the applications of the BDFM in WECS. The robust control strategy based on sliding mode theory is applied for the independent control of active and...
In the paper, a novel principle of variable reactor with a transformer and inverter control is proposed. A transformer with air gap is chosen and its primary winding is connected in series or parallel in power utility, the primary winding current of the transformer is detected and functioned as the reference signal. A voltage source PWM inverter is applied to produce a voltage, which is a controlled...
This paper presents the flux weakening control method of an open winding machine which is connected to the two isolated inverters. The methods of the current reference modification and the over voltage modulation of two inverters are proposed to enhance the flux weakening control of the open winding machine at high speed. Furthermore, the power flows through two inverters are controlled independently...
