【Abstract】 Composition of an active magnetic bearing (AMB) system and its principle of operation are studied. Design of an expert intelligent PID controller based on traditional PID is presented, and techniques for implementation analyzed. Hardware based on TMS320LF2407A by TI used in the expert intelligent PID control with AMB of 5 degrees of freedom is designed, forming the core part of the system. The basic idea of software design is presented with a flow chart. Part of the design process is described in detail. Theoretical analysis shows that this type of controller can achieve better control with a higher precision.更多还原
