In this paper we develop a robust controller design for the Active Mass Driver (AMD) benchmark problem. The design process is based around the D–K iteration procedure for (complex) μ synthesis, together with a balanced truncation procedure to reduce the controller order. The final design is a third‐order linear controller, which utilizes only four accelerometer measurements, and has desirable rolloff properties (i.e. small required bandwidth, and a high degree of robustness). Despite the simplicity of the controller, it is able to yield quite good performance, while using only modest control authority. © 1998 John Wiley & Sons, Ltd.
