An air bearing gravity unloading facility for the antenna pointing mechanism (APM) is presented which is used to simulate micro-gravity environment for testing the APM on the ground. An artificial load for the APM is presented to simulate the inertia, mass and frequency to reflect the performance of the pointing mechanism. The structure design of artificial load is based on the lexicographic method...
Interior permanent magnet motors (IPM) have been widely used in electric or hybrid electric vehicles due to their high efficiency and high power density. Frequent starts and stops, acceleration and deceleration of vehicles present heavy requirements for the drive motor. In this paper, a 4kW interior permanent magnet motor is designed for a small range-extended electric vehicle. A case study has been...
Over the past several decades, the control of electric machines has typically been viewed using a “black box” approach which typically involves the manipulation of voltage and current to generate desired characteristics. However, for the purpose of designing and controlling the permanent magnet synchronous motor (PMSM) efficiently, a thorough understanding of the magnetic field parameters can play...
According to the magnetic suspension character of the rotor in the new type of gyro, the control mathematic model for the gyro's rotor magnetic suspension system is founded. The system is characterized by its instability ' nonlinearity. In this paper, a variable structure controller is designed. Based on the general variable structure controller theory, the design of switch function using the method...
The technology of measuring the surface of a new type of Gyropsilas rotor is presented in this paper. On the basis of the principle of nice measured drift of differential capacitance sensors and the properties of a transformer electric bridge of changing in real numbers with fine stability, high precision, good sensitivity and wide working frequency range, a measuring scheme, which combines differential...
The magnetic supported system in the new type of Gyro is designed according to the characters of magnetic supported system. A method using additional compensating coil is proposed. It is proved that the rotor suspended in the system is stably suspended. The control mathematic model for Gyro's rotor supported system is founded. The system is characterized by its instability psila nonlinearity ldr In...
