Description

Преалагаемое устройство может использоватьс в комплексе устройств автоматической оптимизации дл вычислени даваемого ими эффекта.The proposed device can be used in a complex of automatic optimization devices for calculating the effect they produce.

Известны устрюйства дл автоматической оптимизации технологических процессов ij, содержащие модель управл емого объекта и систему оптимзации .There are known devices for automatic optimization of technological processes ij, containing a model of a controlled object and an optimization system.

Эти устройства не позвол нуг с высокой точностью Определить основной показатель технологического процесса и, следовательно, степень оптимизации.These devices do not allow high accuracy to determine the main indicator of the technological process and, therefore, the degree of optimization.

Модель объекта оптимизации имеет несколько выходов, каждый из которых св зан с соответствующим входом автокоррел тора . Число входов автокоррэл тора определ етс числом вoз oжныx сдвигов (задержек) входного сигнала. На чертеже показана модель объекта оптимизации с одним выходом. При поступлении сигналов с других выходов устройство работает аналогично.The optimization object model has several outputs, each of which is associated with a corresponding autocorrelator input. The number of autocorrector inputs is determined by the number of return shifts (delays) of the input signal. The drawing shows a model of an optimization object with one output. When signals from other outputs arrive, the device works in the same way.

Claims

The input signal (the signal from the output of the object model) is autocorrelated in the autocorrelator torus 2. One output is auto. the correlator of the torus, the signal from which is not delayed in the autocorrelator, is connected to the multiple input of the adder 3. EiTopofl the output of the autocorrelator of the torus, the signal corresponding to the shift in the autocorrelator of the torus, equal to the optimization delay of the control signal acting on the control object is connected to the input of the block multiply 4 (optional), in which this signal is multiplied by a constant coefficient K (K-a). The output of this multiplication unit is associated with the plus input of the adder 3. The output of the adder is connected to the input of the multiplication unit 5, in which multiplication occurs by a fixed one (the coefficient equal to the parabola coefficient approximating the dependence of the performance quality criterion on the optimized control action under consideration is tuned. On the output of multiplier 5 is obtained a value equal to the effect of the optimization on the slide shem, the time interval that characterizes the degree of optimization. The time element determines with the autocorrelator setting. The proposed device quickly calculates the degree of optimization (the effect of optimization of the object control) and allows you to more accurately determine the main indicator of the technological process in the object's operation mode without turning off the optimization system. optimization degree of objects, containing an optimization object model, an adder and a multiplication unit, characterized in that, in order to increase the accuracy of the device, it also contains Torr connected in sequence autocorrelation and the second multiplier, whose output is connected via an adder to the first multiplying unit, coupled to the input autocorrelation torus yield optimization model object and the other output - to the other input of the adder.
