Optimization of the adaptive function by Z-transform method
Sheldon S. L. Chang · Transactions of the American Institute of Electrical Engineers Part II Applications and Industry · 1960
A study is made on the optimization of the adjustment process in a self-optimizing system under rather general assumptions. The system is designed to keep a performance parameter m either at a prescribed value or at an unknown extremal value. A direct measurement on m is made and the adjustment is based on measured m only.
