ADAPTIVE CONTROL OF A DYNAMIC SYSTEM OR PROCESS

An adaptive control for a dynamic system or process which can be described mathematically as having dominant eigen values and which utilizes the phase response variation with frequency and more precisely uses the rate of change of phase with frequency to measure dynamic characteristics of the system or process and by comparison with known optimum values of rates of change of phase based on a criterion as herein defined determines the changes required to controlled parameters or to a controlling computer in order to achieve and maintain optimum or near optimum performance of the dynamic system or process.
