A method for controlling a fluid system is provided. The system may include a hydraulic circuit having a pump driven by an engine, wherein the pump delivers fluid to an actuator through a valve assembly. The method may include receiving an operator input and determining a condition of the hydraulic circuit. The condition of the hydraulic circuit may include at least one of a flow rate of fluid to the actuator, an engine speed, and a pump displacement. The method may include determining a valve transform function as a function of a position of a linkage associated with the actuator and the condition of the hydraulic circuit. The method may further include determining a valve command in response to the valve transform function and the operator input, wherein the valve command results in a consistent deadband. The valve command is delivered to the valve assembly.
