Searching for Robust Minimal-Order Compensators
A method of designing a family of robust compensators for a single-input/single-output linear system is presented. Each compensator’s transfer function is found by using a genetic-algorithm search for numerator and denominator coefficients. The search minimizes the probabilities of unsatisfactory stability and performance subject to real parameter variations of the plant. As the search progress...
متن کاملRobust Stabilization of Interval Plants using Kronecker Summation Method
This paper deals with design of continuous-time robustly stabilizing Proportional-Integral (PI) controllers for interval systems using the combination of Kronecker summation method, sixteen plant theorem and an algebraic approach to controller tuning. The effectiveness and practical applicability of the proposed method is demonstrated in both simulation and real experiments including control of...
متن کاملLow-order Robust Controller Synthesis for Interval Plants
This paper deals with robust controller synthesis for SISO linear plants subject to interval parametric uncertainty, a longstanding open problem of control theory. Based on Hermite-Fujiwara matrices and the Generalized Kharitonov's Theorem, a necessary and suucient condition is derived for the existence of a robustly stabilizing controller of given order. This condition is formulated as a non-c...
متن کاملRobust Stabilization of Fractional-Order Systems with Interval Uncertainties via Fractional-Order Controllers
We propose a fractional-order controller to stabilize unstable fractional-order open-loop systems with interval uncertainty whereas one does not need to change the poles of the closed-loop system in the proposed method. For this, we will use the robust stability theory of Fractional-Order Linear Time Invariant FO-LTI systems. To determine the control parameters, one needs only a little knowledg...
متن کاملA Robust Kalman Conjecture for First-Order Plants
A robust Kalman conjecture is defined for the robust Lur’e problem. Specifically, it is conjectured that the nonlinearity’s slope interval for which robust absolute stability is guaranteed corresponds to the robust interval of the uncertain plant. We verify this robust Kalman conjecture for first-order plants perturbed by various norm-bounded unstructured uncertainties. The analysis classifies ...
