【Abstract】 The working principle of a new kind of magnetic suspension bearing(MSB) was introduced and mathematic model of this MSB system was established by principles of dynamics and electromagnetic.The relation between stiffness damping and its control system was argued,and through this relation the PID control parameters were determined.Expert-PID controller was developed by utilizing the three parameters of traditional PID controller as the initial parameters of Expert-PID and experiment was carried out on the MSB platform.The results showed that this new control system has satisfactory performance and can suspend quickly and stably under the control of expert-PID.更多还原
