TLDR
In this article, a design procedure is introduced which incorporates loop shaping methods to obtain performance/robust stability tradeoffs, and a particular H/sub infinity / optimization problem to guarantee closed-loop stability and a level of robust stability at all frequencies.Abstract:
A design procedure is introduced which incorporates loop shaping methods to obtain performance/robust stability tradeoffs, and a particular H/sub infinity / optimization problem to guarantee closed-loop stability and a level of robust stability at all frequencies. Theoretical justification of this technique is given, and the effect of loop shaping on closed-loop behavior is examined. The procedure is illustrated in a controller design for a flexible space platform. >read more

Two degrees of freedom PID multi-controllers to design a mathematical driver model: experimental validation and robustness tests
TL;DR: In this article, a mathematical driver model based on PID multi-controllers having two degrees of freedom is proposed, where each PID controller making up this model is synthesized by the Ziegler-Nichols oscillation method, using the linear time invariant models which are obtained around their nominal operating points.

Robust dynamic stiffness design of linear servomotor drives
Bin Hong Shen,Mi-Ching Tsai +1 more
TL;DR: In this paper, the authors employed the H ∞ loop shaping design concept to obtain a so-called advanced pseudo derivative feedback with feedforward (PDFF) controller, which allows dynamic gains in the feedback loop and the pole/zero relationships between the proposed h ∞ controller and the closed-loop system.

Robust flight control system design using H∞ loop-shaping and recessive trait crossover genetic algorithm
TL;DR: A proposed approach to robust controller design is introduced that combines the recessive trait crossover genetic algorithm with the loop-shaping design procedure using H"~ synthesis and reveals that the desired performance objectives are achieved and the controller provides acceptable performance in spite of modeling errors and plant parameter variations.
