摘要:

研究了一种新型的轴流式永磁偏置混合磁悬浮人工心脏结构。在该结构基础上,进行Maxwell磁力仿真与分析,得出了磁悬浮转子的状态数学模型;设计系统控制电路,列劳斯判据表,得到系统控制稳定时的PID参数范围;再通过MATLAB仿真,给出控制仿真结果。研究过程为磁悬浮人工心脏的稳定控制奠定了理论基础。

Abstract:

A new type maglev artificial heart with permanent magnet biased was studied. Based on this structure, simulation and analysis of electromagnetic force by Maxwell software were carried out; the state-space mathematical model of levitation rotor was got; then the control circuit was designed; the Routh Criterion table was listed; PID parameters were ranged under the condition of stability control; results were received through MATLAB simulation. Research process lays a theoretical foundation for artificial heart control system.

Key words: new artificial heart, state-space model, PID controller, simulation
