论文摘要
为二阶系统提出了新型的非线性阻尼控制。比例输出反馈与阻尼项相结合，该术语与输出衍生物二次，与设定点距离相反。展示了全球稳定性，被动率和收敛时间和准确性。也明确分析了控制饱和案例。建议的非线性阻尼表示是最佳的，因为不需要设计其他参数并确保快速收敛，而没有瞬态过度冲击，即用于饱和控制配置的非饱和和一个瞬态过冲。
Novel nonlinear damping control is proposed for the second-order systems. The proportional output feedback is combined with the damping term which is quadratic to the output derivative and inverse to the set-point distance. The global stability, passivity property, and convergence time and accuracy are demonstrated. Also the control saturation case is explicitly analyzed. The suggested nonlinear damping is denoted as optimal since requiring no design additional parameters and ensuring a fast convergence, without transient overshoots for a non-saturated and one transient overshoot for a saturated control configuration.
