  • Control system for a double-acting air cylinder of an agricultural implement
    Patent number: 11930728
    Abstract: A control system for a double-acting air cylinder of an agricultural implement includes a valve assembly configured to control a base end air pressure and a rod end air pressure of the double-acting air cylinder. The control system also includes a controller communicatively coupled to the valve assembly. The controller is configured to determine a target base end air pressure and a target rod end air pressure based on a target force of the double-acting air cylinder and a target damping factor of the double-acting air cylinder. The controller is also configured to control the valve assembly such that a first difference between the base end air pressure and the target base end air pressure is less than a first threshold value and a second difference between the rod end air pressure and the target rod end air pressure is less than a second threshold value.
