This paper discusses a linear-quadratic (LQ) control and nonlinearities compensation of a rotor suspended by active magnetic bearings (AMBs). The control structure is based on a state-space controller with additional integrative feedback, current estimator and disturbance estimator. An effective compensation of performance variations in dynamic force characteristics of AMBs is performed using two...
This paper presents an implementation of an FPGA-based real-time emulator for mechatronic applications. Active magnetic bearings (AMBs) for contactless support of high-speed rotors are selected as a case study. It is shown that for a general class of state-space models with separable nonlinearities, it is possible to build an optimized hardware implementation of the plant emulator or state observer,...
This paper discusses a design and implementation of an application specific architecture of active magnetic bearings (AMBs) controller in a field programmable gate array (FPGA) circuit. As a first step, a prototyping platform that eases development of control, testing and integration of tested algorithms into the FPGA is built. The FPGA implementation of an AMB current controller of a set of ten H-bridge...
