Abstract: A sliding mode control strategy based on inner and outer loops is proposed for the first?class under?actuated quadrotor UAV controlled model, so as to realize stable control and tracking of the Quadrotor UAV system. The dynamics model of the quadrotor UAV is established by using the Lagrange equation. The inner and outer ring control strategy which takes the location system as the outer ring, the attitude system as the inner ring, and the sliding mode control law as the control method is designed according to its mathematical model. The system was simulated in the Matlab environment, by which the effectiveness of the control strategy was verified.

Keywords: under?actuated system; sliding mode control; double closed?loop control; Quadrotor UAV; system simulation;control law

欠驅(qū)動(dòng)系統(tǒng)是指系統(tǒng)的獨(dú)立控制變量個(gè)數(shù)小于系統(tǒng)自由度個(gè)數(shù)的一類(lèi)非線(xiàn)性系統(tǒng),相比而言,欠驅(qū)動(dòng)系統(tǒng)在能耗、成本、結(jié)構(gòu)以及實(shí)用性方面要優(yōu)于全驅(qū)動(dòng)系統(tǒng)[1]。欠驅(qū)動(dòng)系統(tǒng)便于進(jìn)行全面的數(shù)學(xué)建模仿真以及分析,而且由于欠驅(qū)動(dòng)系統(tǒng)存在足夠的復(fù)雜性,例如高度的非線(xiàn)性以及參數(shù)攝動(dòng)嚴(yán)重等,使得欠驅(qū)動(dòng)系統(tǒng)具有典型性[2]。在對(duì)抗非線(xiàn)性系統(tǒng)以及系統(tǒng)參數(shù)攝動(dòng)方面,滑??刂谱鳛橐环N經(jīng)典控制策略,有著強(qiáng)魯棒性,對(duì)系統(tǒng)參數(shù)攝動(dòng)不敏感等優(yōu)點(diǎn),因此采用滑模控制方法來(lái)解決欠驅(qū)動(dòng)系統(tǒng)的控制問(wèn)題[3]。

四旋翼飛行器(Quadrotor UAV)系統(tǒng)是一類(lèi)經(jīng)典的欠驅(qū)動(dòng)系統(tǒng),在本文中以Quadrotor UAV為受控對(duì)象,根據(jù)Lagrange方程建立動(dòng)力學(xué)模型[4],以位置子系統(tǒng)為外環(huán),姿態(tài)子系統(tǒng)為內(nèi)環(huán),通過(guò)設(shè)計(jì)滑??刂坡?,實(shí)現(xiàn)對(duì)航跡及滾轉(zhuǎn)角的跟蹤,同時(shí)保證偏航角以及俯仰角的穩(wěn)定[5]。

5 ?結(jié) ?語(yǔ)

本文在Quadrotor UAV系統(tǒng)數(shù)學(xué)模型的基礎(chǔ)上設(shè)計(jì)一種基于內(nèi)外環(huán)的滑??刂品椒?,從而實(shí)現(xiàn)對(duì)系統(tǒng)期望狀態(tài)的跟蹤控制[10]。通過(guò)Matlab仿真,驗(yàn)證了該算法的可行性,并與經(jīng)典PID控制方法進(jìn)行對(duì)比。仿真實(shí)驗(yàn)表明,采用雙閉環(huán)滑??刂品椒ㄔO(shè)計(jì)的Quadrotor UAV控制系統(tǒng)可以保證系統(tǒng)的魯棒性,姿態(tài)角可以快速有效地跟蹤到期望值,而且穩(wěn)態(tài)誤差較小,具有良好的控制性能,在實(shí)際系統(tǒng)中具有很廣闊的應(yīng)用前景。
