Structural – Parametric Analysis And Synthesis Of Glass Furnace Condition Observer, Utkir Uktam O‘G‘Li Kholmanov

Chemical Technology, Control and Management

A modified Kalman filter of the glass cooking process is synthesized, taking into account perturbations in the form of a sequence of colored noises. The possibility of expanding this filter by noise filters to improve functioning in the presence of low-frequency disturbances is studied and a corresponding estimation scheme with additional noise filters is proposed. The results of the simulation allow us to assume that low-frequency disturbances in the glass furnace act at the input and affect the state of the control object.

Chemical Technology, Control and Management

Mathematical models of thermal processes of traction asynchronous motors are developed. A traction asynchronous motor is considered as a thermal system consisting of three bodies (stator winding, stator magnetic core and rotor), which take into account the heat exchange not only between the corresponding bodies, but also the heat exchange between each body and the environment. It is shown that the steady excess of the stator winding temperature of a traction asynchronous motor depends on the multiplicity of the stator winding current, the coefficient of electrical energy loss, and also on the temperature coefficient of the resistance of the winding …
