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, Poincaré 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.
