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.
