Abstract The goal of this paper is to investigate the complex nonlinear dynamics and its control chaotic behavior in electromechanical valve actuator (EVA). The nonlinear phenomena can be expressed using numerical techniques, such as time responses, phase portraits, Poincare maps, and frequency spectra. Lyapunov exponents and Lyapunov dimensions can be used to confirm chaotic behavior. Finally, state feedback control and dither signal control are applied to suppress chaotic motions effectively.

机电阀门执行器的稳定性分析、混沌路径和淬灭混沌

摘要 本文的目的是研究机电阀门执行器（EVA）中复杂的非线性动力学及其控制混沌行为。非线性现象可以使用数值技术表示，例如时间响应、相图、庞加莱图和频谱。Lyapunov 指数和 Lyapunov 维度可用于确认混沌行为。最后，应用状态反馈控制和抖动信号控制来有效抑制混沌运动。
