ABSTRACT:
A sampled control loop for controlling a process includes a gain optimizer that dynamically adjusts the loop gain transfer function in response to changes in any of the loop sampling interval, process time constants, or transducer propagation delay. The adjustment maintains optimal loop response in spite of those changes. The gain optimizer does this by approximating one or more gain functions which collectively determine the transfer function describing how a gain network generates a process control signal from an error signal.
