Within a mechanical control system, continuous adaptive digital to analog control may control an analog actuated device by comparing a current value for a process variable to a setpoint value to obtain an error value, wherein the process variable may represent a monitored condition controlled by an analog actuated device. Continuous adaptive digital to analog control may also include converting the error value into a digital pulse time value representing a correction to compensate for the error value. The error value may be converted using a gain factor derived from timing characteristics for the actuated device. An analog value may be output based on a previously output value and the digital pulse time value. Continuous adaptive digital to analog control may repeatedly adjust the actuated device according to the changing values for the process variable.
