Description
Summary:This paper solves the problem of designing of regulator for control of complex unstable object. Calculation was done by numerical optimization using control structure comprising bypass channel. The idea of the bypass channel develops the idea of Smith predictor, but, unlike a predictor, its model can be calculated by the more flexible algorithms. Furthermore, this method does not require the presence of a pure delay link in the object model. This makes the bypass channel more flexible and more efficient than a Smith predictor. The object model is taken from list of well-known object models, which are very difficult for the feedback control due to the strong tendency to fluctuations. Earlier attempts to design regulators for this object are unsatisfactory. This paper shows the efficiency of the bypass channel for the said task. The results are confirmed by simulation.
