METHOD FOR OPTIMIZATION OF A TRANSIENT PHENOMENON IN AN AUTOMATIC CONTROL SYSTEM AND THE DEVICE FOR THE REALIZATION OF THE METHOD

The proposed method for optimization of a transient phenomenon in an automatic control system consists in generating the signal that is proportional to the square of the difference of the derivative of the input signal and of the derivative of the output signal of the control system, generating the signal that is proportional to the absolute value of the system error signal, comparing the current values of the said signals so generated, and generating a correction signal with consideration for the sign of the error signal if the current value of the first signal amplitude exceeds the current value of the second signal amplitude within the time interval within which the error signal exceeds a reference signal. The proposed device for optimization of a transient phenomenon in an automatic control system, which contains an error signal measuring unit and an error signal amplifier, contains a correction unit and the frequency rotation transducer of the system actuating motor. The correction unit contains three summing unit, a squaring unit, a rectifier, a relay element, a threshold comparator, a signal sign determining unit, an AND logic element, a differentiator unit, and a multiplier unit. The output of the error signal measuring unit is connected to the input of the rectifier, the input of the signal sign determining unit, and the inverting input of the first summing unit. The output of the first summing unit is connected to the input of the error signal amplifier. The noninverting input of the error signal measuring unit is connected to the noninverting input of the second summing unit via the differentiator unit. The inverting input of the second summing unit is connected to the output of the rotation frequency transducer, and the output is connected to the noninverting input of the third summing unit via the squaringunit. The inverting input of the third summing unit is connected to the output of the rectifier and the input of the threshold comparator. The output of the third summing unit is connected to the inverting input of the first summing unit via the series-connected relay element, AND logic element, and multiplier unit. The output of the threshold comparator is connected to the second input of the AND logic element. The output of the signal sign determining unit is connected to the second input of the multiplier unit.
