Algorithm of subinvariant control of distillation column with disturbance compensation

An algorithm of robust subinvariant control of a distillation column, which mathematical model is represented parametrically and by functionally uncertain linear differential equation, is considered in the paper. The received algorithm is simple both in realization and in calculation of adjusted parameters. The algorithm allows to compensate the uncertainties in the distillation column with a specified accuracy. Numerical examples and results of the computer modeling demonstrating the operational capability of the offered scheme are given.
