新型汽车道路模拟算法研究

传统的道路模拟算法以识别系统的频响函数矩阵为基础，通过在频域反复的迭代使系统的实际响应逼近于期望响应。认为道路模拟系统本质上是一个自动控制跟踪系统，在此基础上提出了一种新的道路模拟时域控制方法——利用最小方差自校正控制器的自适应控制方法。对提出的算法进行了理论推导，并用试验证明这种方法的正确性和实用性。

STUDY ON A NEW VEHICLE ROAD SIMULATION ALGORITHM

Traditional road simulation algorithm is based on the estimation of the FRF matrix of the system and through repeated iteration in frequency domain the real response approximates to the expect response. Road simulation test system is in nature an automatic control and tracking system. A time-domain road simulation algorithm, minimum variance self-tuning controller method, is presented and developed. The algorithm is realized on a personal computer. An experiment on a vibration structure is carried out to validate the correctness and practicability of the method.
