This paper presents a new rotor flux oriented linearizing control with speed estimation scheme for adjustable speed induction motor (IM) drive. In this scheme, rotor flux oriented vector control is used to linearize the IM drive, and decouple torque and flux. Also, a stator flux based flux estimator is used to estimate the synchronous speed. The motor speed is estimated by measuring only two li...

The rotor flux is estirnatcd for a direct field oriented induction machine drive using a voltage-current mode algorithm, or physical based algorithm. The estimated rotor flux is used to synthesize the components of the rotation matrix, szn(@,) and cos(@,). These angles are critical in transforming the command currents to the stationary frame such tha t field orientation is maintained. The princ...

In this paper a sliding-mode torque and flux control is designed for encoderless synchronous reluctance motor drive. The sliding-mode plus PI controllers are designed in the stator-flux field oriented reference frame which is able to track the mentioned reference signals with a minimum pulsations in the state condition. In addition, with these controllers a fast dynamic response is also achieve...

Community-oriented primary care (COPC) combines elements of clinical medicine and public health to provide an effective strategy in tackling today's health problems. A primary care practice or program that develops a partnership with an identified community to describe and prioritize health concerns and design and monitor the impact of an intervention can make a difference to the health of a co...

A detailed model of wind power station, including Double Fed Induction Generator, DFIG is presented in this paper. Two control mechanisms are included in the model. The inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. The outer control system is used for wind turbine pitch angle. PSCAD/EMTDC is us...
