基于生物内分泌系统激素调节机理设计了内分泌智能控制器，结合传统的线性二次型调节器（LQR），提出一种新型复合结构的内分泌LQR控制器。将其应用于汽车主动悬架减振控制，采用ADAMS/View构建麦弗逊汽车悬架模型，以典型的正弦路面输入和随机路面输入作为激励，通过MATLAB与ADAMS联合仿真对比分析了内分泌LQR控制、传统LQR控制及被动悬架的减振效果。研究结果表明，内分泌LQR控制品质优良、对变化的工况参数具较好的适应性,减振效果要优于传统LQR控制。该方法为主动悬架减振提供了一种新的控制方案，同时也为内分泌智能控制策略及其应用提供了新思路。
Abstract
By combining the traditional linear quadratic regulator (LQR) with the endocrine intelligent controller which is based on the endocrine hormone regulation principles, a new compound endocrine LQR controller is proposed. The proposed strategy is then applied to the vibration control of vehicle active suspension, in which a Mcpherson suspension mode is established in ADAMS/View. With sine and random excitations as typical road input, comparison is performed among the endocrine LQR, LQR and passive suspensions by means of the co-simulation of ADAMS and MATLAB. Simulation results demonstrate that the proposed endocrine LQR is superior to LQR, and has advantages of excellent performance, strong adaptability. The proposed control strategy not only provides a new control scheme for active suspension, but also a possible new way for endocrine intelligent control and its applications.
