362 results about "Effective action" patented technology

In quantum field theory, the effective action is a modified expression for the action, which takes into account quantum-mechanical corrections, in the following sense: In classical mechanics, the equations of motion can be derived from the action by the principle of stationary action. This is not the case in quantum mechanics, where the amplitudes of all possible motions are added up in a path integral.

The invention discloses a feed-forward voltage compensation-based direct-current side oscillation suppression method for a metro traction converter. Proper damping parameters are selected according toa stability criterion condition. Meanwhile, based on the principle that the ratio of effective vectors is maximum and the disturbance is minimum, a feed-forward voltage compensation parameter of a dqshaft is calculated. According to the principles of equal effective action vectors and power conservation, a reference voltage vector after the amplitude-limiting adjustment is obtained through calculation. As a result, the direct-current side stability control of a metro traction transmission system under the compensation over-modulation condition is ensured. According to the invention, the dynamic compensation for the feed-forward voltage is adopted, and the oscillation of the direct-current side voltage and the direct-current side current during the operation process of the traction transmission system is suppressed.
