Abstract:
A control system for mixing materials having a container to receive the materials, agitators, a driveline to drive the agitators at an output speed with an output torque, an power source to provide an input speed with an input torque, a continuously variable transmission that connects the driveline and the power source, and an electronic control unit configured to adjust a speed ratio of the continuously variable transmission to provide a linear relationship between the input torque and the output torque with a slope, when the input torque is below a control input threshold, and to follow a corrected linear relationship between the input torque and the output torque with a corrected slope smaller than the slope when the input torque is above the control input threshold.
