A QFT Approach to Control of Active Suspension Systems

In this paper, Quantitative Feedback Theory (QFT) is applied successfully to design a controller for benchmark problem, “Design and ptimization of restricted complexity controllers”, for an active suspension system. Design goals are defined as constraints on frequency domain response. A low-order controller is designed to provide attenuation of disturbances in spite of practical limitations on the achievable closed-loop performance. Complexity and accuracy of designed controller is compared with result of several control approaches for the same benchmark.
