ABSTRACT:
An open-loop system for controlling a plant, including a sampling circuit for providing an actuating signal as a series of impulse signals, and a computer for providing a control signal to operate the plant in response to the actuating signal in accordance with a control function defined by a control algorithm based upon a calculated response of the plant in an equivalent closed-loop linear control system. The computer provides the control signal as a function of time following the application of each impulse signal. The control algorithm is a time-domain algorithm based upon an inverse LaPlace transform of the equivalent system. The interval between impulse signals, as defined by the sampling rate, is on the order of the time constant of the equivalent system; and the computation speed of the computer is sufficiently fast to provide a control signal that is effectively continuous relative to the operating dynamics of the plant.
