Using analog/digital mixed simulation tool-PSpice,the RFS system output response was analysed and validated under the condition of open loop and closed loop.

For the System,the main frequency is controlled by a computer and motor control mode is controlled by open loop and closed loop governing system of vector control. It realizes intercommunicate connection technoloyy between the computer,inverter and motor and realizes remote monitoring.

For multiple transmit and receive antennas,both open loop and closed loop capacity regions are assessed, where the closedloop capacity assumes channel state information at the transmitter and optimumpower allocation.

This extension has been derived for both open loop and closed loop systems of flexible bodies.

We also use regular open-loop and closed-loop observations where we get both xand y-slopes with a single algorithm.

We often use the terms open loop and closed loop when referring to such systems.

In this paper, the system open-loop and closed-loop characteristic curves, power factor curves, efficiency curves and test waves are also give. Experimental results indicate that this system can greatly improve IM operating performance as well as rise IM power factor and efficiency. The power factor rises to 0.94 and the efficiency rises to 0.92 in total power output range. Under identical conditions, as compared with non-capacitive compensator system, the total efficiency of this system rises about 3%.

A novel PWM based static VAR compensator (PSVC) is introduced. In a single generator infinite system, the one order inertia model of PSVC is derived with the small disturbance method. The theoretical analysis indicates that PSVC, compared with other SVCs, such as TCR and TSC, can compensate the reactive power more rapidly and accurately with little harmonic. Therefore it can stabilize the system voltage efficiently. The digital simulation results of the open loop and closed loop...

In vector control of induction motor, the key problem is to estimate rotor flux accurately. However, the accuracy of traditional flux estimators will be degraded due to perturbations of stator or rotor resistance. This paper proposes a rotor flux estimator based on stator current vector orientation. The novel estimator contains neither stator nor rotor resistance. Therefore, the influences on flux estimation accuracy, caused by resistance parameter perturbations, are avoided. The open-loop and closed-loop...

In vector control of induction motor, the key problem is to estimate rotor flux accurately. However, the accuracy of traditional flux estimators will be degraded due to perturbations of stator or rotor resistance. This paper proposes a rotor flux estimator based on stator current vector orientation. The novel estimator contains neither stator nor rotor resistance. Therefore, the influences on flux estimation accuracy, caused by resistance parameter perturbations, are avoided. The open-loop and closed-loop simulation results show that this flux estimator has very high accuracy. Furthermore, large perturbations of stator and rotor resistances have few influences on estimation results. The novel flux estimator shows stronger disturbance-rejecting capability than the traditional ones.
