WebThe basic concept of feedforward control is to measure important disturbance variables and take corrective action before they upset the process. The disturbance variables must be measured on-line. In many applications, this is not feasible. To make effective use of feedforward control, at least an approximate process model should be available. WebFeedforward control design, especially for non-minimum phase systems.
