Dynamic Modeling and Simplified Analysis of EMA Pitching Mechanism

Aiming at the complexity of dynamic model EMA pitching mechanism and feasibility simplification, this paper discusses influence rocker pushrod on characteristics effectively simplifies basis ensuring accuracy. Firstly, a simplified is established based Lagrange equation, equivalent inertia, force arm. Then, in pitch range, inertia arm are converted into load respectively, error compensation established. Finally, position closed-loop control after PID optimal parameter setting, prototype clarified. In paper, value solution method improves accuracy by 92%. The judgment can judge mechanism.
