20140294601 | ACTIVE ADAPTIVE HYDRAULIC RIPPLE CANCELLATION ALGORITHM AND SYSTEM - Hydraulic pumps/motors are used to convert between rotational motion/power and fluid motion/power. Pressure differential is achieved across the pump/motor by applying torque to either aid or impede rotation which generally results in either a pressure rise or pressure drop respectively across the unit. This torque is often supplied by an electric motor/generator. Especially in positive displacement pumps/motors this pressure differential is not a smooth value but rather it contains high frequency fluctuations known as pressure ripple that are largely undesirable. With thorough analysis it can be discovered that these fluctuations occur in a predictable manner with respect to the position (angular or linear) of the pump/motor. Using a model that contains this information, a feed-forward method of high-frequency motor torque control is implemented directly on the hydraulic pump/motor by adding to the nominal torque, a model-based torque signal that is linked to rotor position. This high-frequency signal acts directly on the hydraulic pump/motor to reduce or cancel the pressure/flow ripple of the pump/motor itself without the need for any secondary flow generating devices. | 2014-10-02 |

When the period of the voltage across the motor terminals returns to substantially the same as the period of the line voltage, the line voltage is switched on or reapplied to the motor. | 2014-10-02 |
