TY - JOUR TI - Applying numerical control to analyze the pull-in stability of MEMS systems AU - Zhang Yanni AU - Han Yiman AU - Zhao Xin AU - Zhao Zhen AU - Pang Jing JN - Thermal Science PY - 2024 VL - 28 IS - 3 SP - 2171 EP - 2178 PT - Article AB - The micro-electro-mechanical system is widely used for energy harvesting and thermal wind sensor, its efficiency and reliability depend upon the pull-in instability. This paper studies a micro-electro-mechanical system using He-Liu [34] formulation for finding its frequency-amplitude relationship. The system periodic motion, pull-in instability and pseudo-periodic motion are discussed. This paper offers a new window for security monitoring of the system reliable operation.
