研究了基于生物启发非线性方法的主动悬架系统自适应控制的节能设计问题。针对非线性悬架系统，提出了一种基于生物动力学的自适应跟踪控制方法。在许多现有技术中，一个重要的努力是用于抵消由悬架固有非线性传递的振动能量以改善乘坐舒适性。与现有的方法不同，所提出的方法充分利用了有益的非线性刚度和阻尼特性的启发肢体运动动力学的生物系统，以实现有利的非线性悬架性能与潜在的更少的能量消耗。所需的生物启发的非线性动力学的稳定性分析进行的李雅普诺夫框架内。理论分析和仿真结果表明，在相同的基本控制方法和路面不平度随机激励条件下，所提出的基于生物启发非线性动力学的自适应控制器对汽车的能量消耗量有显著影响，可获得相似的乘坐舒适性.
This paper investigates the energy-efficiency design of adaptive control for active suspension systems with a bioinspired nonlinearity approach. To this aim, a bioinspired dynamics-based adaptive tracking control is proposed for nonlinear suspension systems. In many existing techniques, one important effort is used for canceling vibration energy transmitted by suspension inherent nonlinearity to improve ride comfort. Unlike existing methods, the proposed approach takes full advantage of beneficial nonlinear stiffness and damping characteristics inspired by the limb motion dynamics of biological systems to achieve advantageous nonlinear suspension properties with potentially less energy consumption. The stability analysis of the desired bioinspired nonlinear dynamics is conducted within the Lyapunov framework. Theoretical analysis and simulation results reveal that the proposed bioinspired nonlinear dynamics-based adaptive controller has a significant impact on the amount of energy consumption, considering the same basic control method and random excitation of road irregularity for a similar ride comfort performance.
