In the paper the contour level adjustment five-block evaporating sugar factory settings, described a system of linear differential equations of the fifth order. Since the facility operates under uncertainty, both parametric and structural, for the construction of the system is necessary to use robust stabilization controller that synthesized Loop Shaping algorithm, uniting frequency approaches and H-optimization. It uses numerical methods for finding the minimum of Н∞-norm the difference between open-loop transfer matrix system and transfer the desired matrix on the set stabilization feedback. A closed system with synthesized regulator has low sensitivity and function reproduces the signal problem at the operating frequency, which resulted in reasonably logarithmic amplitudefrequency characteristics (AFC). Since synthesized regulator has a high order, his order was reduced without significant loss of properties. Simulation system with full controls and reduced order with uncertainties and no, demonstrated high quality characteristics transients signals with different objectives, confirming the feasibility of using this approach.
