【摘要】：新型線控液壓轉(zhuǎn)向系統(tǒng)與原轉(zhuǎn)向系統(tǒng)相比,具有很多突出的優(yōu)點(diǎn),其在工程車(chē)輛上的應(yīng)用目前處于初級(jí)階段,且其控制方式常采用傳統(tǒng)的PID控制,但是轉(zhuǎn)向系統(tǒng)具有低阻尼、非線性等性質(zhì),所以傳統(tǒng)的PID控制不能達(dá)到良好的控制效果,從而常出現(xiàn)轉(zhuǎn)向滯后不穩(wěn)等問(wèn)題。因此,設(shè)計(jì)了適合該系統(tǒng)的模糊自適應(yīng)PID控制算法,目的是解決轉(zhuǎn)向滯后和轉(zhuǎn)向不穩(wěn)等問(wèn)題,其進(jìn)一步提高該系統(tǒng)的動(dòng)態(tài)特性。該設(shè)計(jì)通過(guò)Simulink與AMESim聯(lián)合仿真,對(duì)比相同輸入信號(hào)下的兩種控制對(duì)該系統(tǒng)動(dòng)態(tài)特性影響。結(jié)果表明:本設(shè)計(jì)算法的響應(yīng)速度比原來(lái)算法的響應(yīng)速度大約提高了0.5s,且基本無(wú)超調(diào),動(dòng)態(tài)特性較好。
[Abstract]:Compared with the original steering system, the new type of wire-controlled hydraulic steering system has many outstanding advantages. Its application in engineering vehicles is at the primary stage, and its control mode is usually controlled by traditional PID control, but the steering system has low damping. Because of the nonlinear properties, the traditional PID control can not achieve a good control effect, which often leads to the instability of the steering lag. Therefore, a fuzzy adaptive PID control algorithm suitable for the system is designed to solve the problems of steering lag and instability, which can further improve the dynamic characteristics of the system. The design is simulated by Simulink and AMESim, and the influence of two kinds of control under the same input signal on the dynamic characteristics of the system is compared. The results show that the response speed of the proposed algorithm is about 0.5s faster than that of the original algorithm, and there is basically no overshoot, and the dynamic characteristics are better.
