Continuous adaptive digital to analog control

A method, comprising:

• performing, by a control device:
• monitoring a condition of a system controlled by an analog actuated device;
• and
• adjusting a performance state of the analog actuated device based on said monitoring;
• wherein said monitoring comprises comparing a current value for the monitored condition to a setpoint value for the monitored condition to obtain an error value;
• and
• wherein said adjusting comprises:
• converting the error value into a digital pulse time value, representing a control correction for the analog actuated device to compensate for the error value;
• and
• determining a new control value for the analog actuated device based, at least in part, on the digital pulse time value.

A non-transitory, computer-readable storage medium storing program instructions that when executed on a control device cause the control device to perform:

• determining a digital pulse time value based at least in part on timing characteristics of an analog actuated device and on a current value for a monitored condition controlled, at least in part, by the analog actuated device;
• converting the digital pulse time value into an analog signal for driving the analog actuated device to adjust the monitored condition toward a setpoint value for the monitored condition;
• and
• repeating said determining and said converting to continue to adjust the monitored condition toward the setpoint value.
