Abstract

Design, testing and validation of a real-time control hardware and software for active magnetic support of high-speed rotors is a very demanding engineering task. Firstly, this paper introduces the problems of proper diagnostics of a digital control system. Secondly, it presents an alternative way of real-time testing of such a control without the presence of the control plant, e.g. rotating shaft supported by an Active Magnetic Bearing (AMB) control system, itself. The article presents an Field Programmable Gate Array (FPAG) implementation of the AMB-rotor model. Two alternative implementations of an AMB non-linear force field are described. The optimized hardware realization of the rigid rotor in a state-space form is presented. A thorough description of a discrete representation of the state-space model and used per-unitvalues are given. The paper is concluded by a discussion about the implementation of a flexible rotor model.
