METHOD FOR PRODUCTION OF PROPORTIONAL INTEGRATION FUNCTION FOR REGULATION AND DIAGNOSTICS OF AUTOMATIC SYSTEM Russian patent published in 2000 - IPC

FIELD: automatic control. SUBSTANCE: method involves measurement of absolute value of input signal, which is proportional to regulation error, comparison of this value to threshold value. When absolute value of input signal is not greater than threshold value, then method involves integration of input signal. Otherwise, if absolute value is greater than threshold value, then method involves integration of difference of input signal and signal, which is proportional to result of integration, adding input signal to integration result and scaling sum. In each case, when absolute value of input signal is greater than threshold value, method involves measurement of its duration τ₁ and durations τ_i, i = 2,...,n for next n-1 excesses, which conform to condition τ_i∈ T_d,, where T_d is given time. Then method involves checking conditions τ₁≥ T_d and τ₁≤ τ₂≤...≤ τ_n. When one of these conditions holds, system emergency signal is generated. EFFECT: improved quality of control processes, possibility to monitor system state. 5 dwg
