Patent number: 9486825Abstract: A control system is disclosed having at least one spray head, a fluid pump, and a power converter driving the fluid pump. The control system may also have an interface device to receive at least one parameter associated with a desired fluid delivery event, a pressure sensor configured to generate a first signal, a travel speed sensor configured to generate a second signal, and a controller. The controller may be configured to determine a desired fluid pressure based on the at least one parameter, and determine a control command for the power converter based on the desired fluid pressure. The controller may be further configured to determine a feedforward gain parameter based on the at least one parameter and the second signal, determine a feedback gain parameter based on a difference between desired and actual fluid pressures, and adjust the control command based on the feedforward and feedback gain parameters.Type: GrantFiled: August 29, 2012Date of Patent: November 8, 2016Assignee: Caterpillar Inc.Inventors: Khanh T.

Patent number: 6726293Abstract: Star carrier roller assemblies have been used in certain tracked mobile machines, such as those used in the timber industry, that must operate in cold weather and/or over rough terrain. Due to interaction of the star carrier roller assembly with a track chain assembly, undesirable wear on the star carrier roller assembly occurs. The present invention includes at least one star carrier roller assembly for a tracked mobile machine that limits the wear on the star carrier roller assembly. The star carrier roller assembly includes a carrier roller positioned adjacent to a sprocket having a plurality of teeth. Each tooth includes a tooth width and a tooth angle. A ratio between the tooth width and a difference of a pitch length and a bushing diameter of a track chain assembly is less than 0.3, and the tooth angle is greater than or equal to zero degrees (0°).Type: GrantFiled: August 12, 2002Date of Patent: April 27, 2004Assignee: Caterpillar IncInventors: Peter W.
