Abstract

The article presents outcomes of optimizing a distributed control system for objects with distributed parameters. Variational method was applied while optimization. Transfer functions are obtained for main channels of disturbances and controls. To describe processes in the time domain, a Laplace numerical method of inverting the transform is used. Numerical experiment for heat exchange systems of a counterflow heat exchanger is demonstrated. Various controllers have been tested in automatic control systems. Efficiency of distributed control of aeon of single-circuit and double-circuit control systems is shown. In this case, acceleration curves were obtained at the output of the control object. Distributed control functions are also highlighted. The numerical method provides an iterative calculation process with a fairly small number of iterations
