Robust Control of Multi-Connected Technological Objects With Input Delays

Abstract

A task how to manage a multi-connected technological control object with input delays in direct connections and cross-connections with parametric uncertainty and uncertainty of inputs of values of delays is discussed. To solve the task, a new method of compensation of crossconnections is suggested. The method is based on construction of special rated tracking systems for each control channel, in each system the effect of cross-connections on the considered main loop is simulated. It is shown that the robustness of compensation systems is the same as the robustness of the considered main loop, that's why it's necessary to solve the problem of robust management when building regulators. This task is solved within traditional control laws, which are mainly used in automation of technological processes.
