ABSTRACT:
Predictive control of a controlled dynamic system having conventional feedback. The input predictor processes the assumed inputs to the controlled system to determine an error output or value corresponding to the outputs only at the prediction horizon interval. The error output is processed by scalar mathematical operations to adjust the assumed inputs and form actual inputs to the controlled system. This method of predicting the inputs can be accomplished in less time than required by previous systems, and the stability of the controlled system, particularly non-minimum phase systems, is improved.
