Robuste Regelung stellt einen für die praktische Umsetzung wichtigen Aspekt der Regelungstheorie dar. Sie gibt Auskunft, ob die Einschwingvorgänge linearer Regelsysteme rasch abklingen. Dies ist wichtig bei realen Systemen, bei denen sich starke Ä

In an engine out/engine failure of an aircraft the human pilot has to compensate a yaw disturbance torque. Because of a delayed reaction possibly followed by an overreaction the pilot may cause high loads (shear forces) at the vertical tail. These sh

The parameter space approach is extended to a certain class of quasipoly-nomials to compute stable regions in the space of controller and plant parameters. E.g., this quasipolynomial results as the characteristic function of PID controlled linear tim

A typical uncertainty structure of a characteristic polynomial is P(s)=A(s)Q(s)+B(s) with A(s) and B(s) fixed and Q(s) uncertain. In robust controller design Q(s) may be a controller numerator or denominator polynomial; an example is the PID controll

Two main approaches to robust control are the parametric and frequency domain approaches. The aim of this paper which starts with tutorial sections on both approaches is to compare and establish links between the parameter space method of the paramet

This paper is devoted to the problem of simultaneous stabilization of linear plants. It is shown that four given plants p"i(s),i=1,2,3,4 are simultaneously stabilizable if and only if there exist four stable polynomials H"i(s),i=1,2,3,4 which simulta

Given a parametric LTI system, the set of parameters for which all roots lie in a prescribed region Γ in the complex plane can be determined. In a similar fashion conditions for the Nyquist plane, e.g. the Nyquist stability margin, can be mapped int

This paper describes a robust control design for automatic steering of passenger cars. Previous studies [l-3] showed that' reliable automatic driving at highway speed may not be achieved under practical conditions with look-down reference systems whi

Many plants have large variations in operating conditions. To ensure smooth running it is essential to find a simple fixed gain controller that guarantees rapidly decaying and well-damped transients for all admissible operating conditions. Robust Con
