INVESTIGATING ONE CLASS OF EXTREMUM SYSTEMS OF DISCRETE ACTION UNDER THE INFLUENCE OF RANDOM INTERFERENCES,
Abstract
An automatic-control system in which the sampled signal is used for both controlling the actuator and forming the control law is theoretically considered. It is assumed that: the plant is first-order linear; the sampling period is much longer than the total time of control operations. It is found that considerable deviations from the absolute optimum do not seriously affect system accuracy; the latter increases up to a certain value of gain; beyond that value, the extremum-tracking error becomes higher again because of the increased hunting amplitude. Recommendations for selecting the optimal system gain are given. Formulas are developed for the steady-state error of the sampling-data system subjected to noise; in these formulas, the plant inertia is allowed for.
