Abstract :
Active magnetic bearings (AMBs) are an example for industrial applications of digital signal processors (DSPs). The complex control functions involved include multichannel control in a delay-time sensitive system. DSPs are well suited for this challenging application. Hardware and software issues are discussed. Unbalance compensation and other additional functions of the controller are presented. An industrial milling spindle with AMBs and DSP control is discussed in detail. A section on AMB research projects with DSP control indicates future trends
