摘要： The present invention relates to a generator control system that includes a generator, a variable displacement pump, a generator speed sensor, and a generator speed controller. The generator speed sensor generates a measurement output signal that corresponds to the speed of the generator. The generator speed controller generates a control signal that controls the displacement of the displacement pump to limit generator speed surging. The generator speed controller applying default commanded event control gain values to the control signal when a commanded change in the load or speed of the engine or generator occurs, applying uncommanded event control gain values to the control signal in the absence of a commanded change in load or speed of the engine or generator, and reducing the uncommanded event control gain values as needed until the magnitude of generator speed surging is less than a threshold value or until a minimum uncommanded event control gain value threshold is reached.

摘要： A continuously variable transmission (30) is provided having a driven element. The continuously variable transmission also has a first operator input device (22) configured to transmit a first displacement signal corresponding to a displacement of the first operator input device. The continuously variable transmission further has a second operator input device (24) configured to transmit a second displacement signal corresponding to a displacement of the second operator input device. In addition, the continuously variable transmission has a third operator input device (26) configured to transmit a transmission operating mode request. Furthermore, the continuously variable transmission has at least one sensor (46) configured to sense at least one parameter indicative of an operating condition of the transmission. Additionally, the continuously variable transmission has a controller (32) configured to determine a driven element output request based on the operating request mode, the first displacement signal, the second displacement signal, and the at least one sensed parameter. The controller is also configured to regulate an output of the driven element in response to the operating mode request, the driven element output request, and the at least one sensed parameter.

摘要： An asphalt density estimation system includes a measurement device configured to output a measurement signal; a time synchronization unit configured to sample the measurement signal to obtain a sampled measurement signal and identify periodic sampling points of the sampled measurement signal across a plurality of periods. The system also includes a time synchronous averaging unit configured to construct a modified measurement signal in the time domain by: for at least one sampling point within the period, averaging a plurality of the periodic sampling points across periods to obtain an average periodic data point for the at least one sampling point, and constructing the modified measurement signal using the average periodic data point for the at least one sampling point. The system further includes a density calculation unit configured to determine asphalt density values based on the modified measurement signal; and a display unit configured to display the determined asphalt density values.
