ARTICLE ANNOTATION

quote
The paper considers issues of formalization of the process of heat treatment of garments on a heat press to study the features of the process under consideration, and creates control systems for this process. For this purpose, the designs of the heat process were first studied, based on which the construction of an equivalent circuit of the process in the form of electromechanical circuits was proposed. Using the Kirchhoff law, the transfer function of the heat press was determined, and multilayer pads were decomposed. In this case, each layer is presented as a first-order differential equation, i.e., they are presented as a first-order inertial unit. Having modeled such a structural diagram on an electronic analog computer, according to the methodology of the work, the authors obtained acceleration curves and the dynamics of self-oscillations of temperature on the working surfaces of the pads when using various systems of two-position automatic controllers in the open position of the press and the presence of technological disturbances. Interestingly, automatic controllers using electric temperature sensors can be directly included in the circuit of a computer simulating a thermal plant. In this way, the maximum approximation of the operating conditions of the automatic temperature control system to real ones is achieved, which makes it possible to select the optimal parameters for setting the controller and the location of the temperature sensor in the pad.
