Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Optimization of the linear robust systems Soldatov V.V., Yudin A.A., Goncharov A.V. The method of optimization is developed on the basis of integral quadratic criterion for linear stationary systems on which perturbation with unknown characteristics impacts. Application of the given method allows choosing such values of an oscillation index for systems with various kinds of regulators at which the correct balance between filtering and intensifying properties is reached on the range of low and resonant frequencies.
