METHOD FOR AUTOMATIC PROPORTIONAL CONTROL WITH ADAPTIVE SAMPLING INTERVAL AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2013 - IPC G05B11/38 

FIELD: physics.

SUBSTANCE: moments for generation of a control signal are spaced apart by unequal time intervals, wherein the value of the i-th time interval is selected from the expression Δ_i=max(kε_i, Δ_min), i.e., each next moment for generation of the control signal is spaced from the previous by a time interval which is proportional to the modulus of the error signal, which is not shorter than the minimum possible step Δ_min based on operating conditions of the system. The technical result is also achieved due to that the apparatus which realises the method, which has a subtractor whose inputs are connected to a setting device and the output of the control object, and the output is connected to the proportional controller of the sampling action, the control input of the proportional controller of the sampling action is connected to the output of a clock generator and the output is connected to the input of the control object, further includes a unit for selecting the maximum signal and a constant signal source Δ_MIN, the unit for selecting the maximum signal is connected to the input of the clock generator, the first input of which is connected to the constant signal source Δ_MIN, and the second input is connected through a unity-gain amplifier to the output of the subtractor.

EFFECT: improved dynamic properties of the system for automatic control while reducing sensitivity of the system to sensor noise, variation of parameters of the object and settings of the controller.
