Improving PID-Control of AMB-Rotor System Design II: Experimental Results
Most of the industial active magnetic bearings (AMBs) are controlled by PID-Controllers. Usually a time-consuming trial and error procedure is involed to design those PID-Controllers. In part I of this contribution an optimization strategy is introduced to design a complex PID-Controller structure of higher order to be applied on an industrial AMB system. For validation purposes, the selected optimal controllers obtained by using an optimization strategy are applied to a test-rig with a flexible rotor supported by AMBs. In part I of the contribution the control algorithm parameters are optimized, in this part II, the resulting control is implemented on a Digital Signal Processor (DSP) controlling the AMB-rotor system. In combination with a test-rig experiments are performed. Within this contribution various aspects of the implementation are discussed; results are shown.
