Abstract
To produce a desired wave form, the required input control signal to a system mustbe known. If, for a repetitive duty cycle, the output and input signals of the system may be represented by quantize patterns, then the relationship between the input and output at any given point ofthe pattern can be considered as a simple gain. Thus, multiple independent gains (MIG) can be used todefine the complete pattern. If the gains at each point can be determined, the output of the system can be made to follow the desired pattern regardless of the linear or nonlinear nature of the system. This concept has been applied to direct both a linear analog system as well as an electrohydraulic system to follow a specified low frequency (0.1 Hz) repetitive pattern. The paper concludes with a discussion of the limitations and potential of the MIG concept.
