【摘要】 根据转向系统的助力性能要求,对电动助力转向器的控制策略进行了研究。以模糊自适应PID控制为基础,结合神经网络控制算法,实现助力控制。在此基础上,设计了新型的试验台架,以更好的模拟车轮转向过程。结果表明,采用该控制策略能获得较好的转向轻便性和抗干扰性,同时提高了转向系统的稳定性。更多还原

【Abstract】 According to the power-assisted request of steering system,some research on EPS control scheme has been done.The PID control method which is based on fuzzy auto-turning technique and nerve-net are combined to realize assisting control.Based on analyse above,a new test-bed was designed.It can simulate the pocess of steering better.The results show that this control scheme can lighten steering torque and restrain disturbing signals which come from tyre,at the same time,the stability of steering system is improved.更多还原
