This paper investigated a new type of operating mechanism in which the high voltage circuit breaker (HVCB) is driven by a permanent magnet synchronous motor (PMSM). This type of mechanism has high reliability due to its simple mechanical structure. In addition, the operating process of the mechanism is controllable. In this paper, the control technique of PMSM was introduced. A simulation model of...
This paper presents a methodology for extracting useful spatial signals using the motor drive as the sensor during servo operation. Spatially dependent phenomena yield non-stationary frequency content during servo operation. With variable frequency and frequency dependent amplitude in the current and torque signals, the underlying, valuable spatial information is difficult to extract using conventional...
Cornering stability of 4 wheel drive hybrid electric vehicle has been analyzed and improved, where the front motor and the rear motors are used to drive the vehicle. For the control of the motors, a model reference sliding mode controller is designed to generate the additional yaw moment for the vehicle. The algorithms for the motor driving and the yaw rate control for the 4 wheel drive hybrid electric...
