The Parameter Optimization of the PID and PIDD Controller for a Discrete Object
Development of the theoretical and numerical
methods in the theory of automatic control expands the class of
control objects for which effective regulators have been found.
Every time researchers find a solution to class of problems, the
area of problems that have solutions is expanded. In contrast, the
area of problems without solution is reduced. Unfortunately,
nobody save a careful record of solved problems sometimes leads
to duplication of research. It is wasting time and money.
Therefore, before solving of a certain class problem every
researcher must carefully study all the methods for solving
problems for this class. There is not scientific result if the
proposed solution is less effective than the existing one. Even if
the proposed solution effectiveness is equal to existing wellknown
methods, the new solution is not essential for the
development of science, unless a class of problems is found for
which the proposed solution is more effective than others. This
paper discusses solution of design a discrete controller for a
discrete object. The object model is taken from paper where
calculations were carried out according to the Ziegler–Nichols
method. The insufficient efficiency of this method is shown, and
the exceptional efficiency of the numerical optimization method
with modified target functions is demonstrated. Also we consider
a complicated example of the object for which the effective
regulator has been found. Some recommendations for the
proposed method using to the such objects are given.
