Abstract. For the problem of parametric identification of control objects proposed a method based on the use of artificial neural network feedforward type a perceptron. This method allows us to estimate the parameters of the mathematical model of the system with a maximum error of 2.8% and significantly reduce the time of the identification procedure.

Abstract.The description of degree model of reliability of the heat power equipment in which as a factor of loading the working temperature of the equipment is used is provided, interval estimates of constant values of model are given. For a row of elements of constructions of boilers dependences of the relative increase in failure density are given by operation in the conditions of the increased temperatures for a long time.

Abstract. Design of the automatic liquid level control was performed for the tank rectangular type with the presence of self-regulation. Were found settings of two-position automatic controller with a zone of ambiguity with symmetric static characteristic. Settings meet the specified requirements for the automatic control system. Opportunities and stability of self-oscillations of the controlled variable were assessed by the method of harmonic balance. Was created a virtual model of single-circuit system two-position control of liquid level and estimates the quality of regulation.
