航空快速电磁阀的设计和仿真研究

根据某小型发动机控制系统改型需要设计了小电压、小流量快速电磁阀取代原有的液压调节阀,以动态电磁方程为基础对其核心的电磁部分进行了参数设计计算;并以流量连续方程和力平衡方程为基础建立了整个电磁阀的微分形式的数学模型,由MATLAB中的simulink软件直接进行仿真研究和参数分析。研究结果表明:所设计的快速电磁阀,响应速度快,工作稳定、控制精度高,完全满足设计要求,证实了方法的有效性和准确性;直接由微分方程仿真的方法既避免了惯用的小增量线性化对非线性系统的影响,也能实时修正非线性元件和系统的非线性参数,对工程动态设计、反设计、优化提供了依据。

Design and Simulation of Aero-High-Speed Solenoid

A low voltage and small flux high-speed solenoid was designed to meet the remodel needs of a mini-type engine control system for replacing the hydraulic adjustor. It calculates and tests the parameters of the core parts of the solenoid---the electromagnet and the spring; then establishes a mathematic model of the whole valve with the flux continuum equation and power balance equation,which is simulated and analyzed with Simulink of MATLAB. The results of simulations indicate that the designed solenoid satis...
