摘要
在四旋翼飞行器控制系统优化问题的研究中,四旋翼飞行器时常会受到外界扰动而易出现抗干扰能力差、控制精度低等问题。针对上述问题,设计了一种以反步法为基础,结合自适应原理,引入积分环节的增稳积分反步自适应位置控制算法,为减少系统响应时间,根据切换控制的思想,设定限定调节带状区域,用以判定是否加入积分环节。在姿态控制上,采用反步鲁棒自适应控制算法进行控制。将四旋翼飞行器控制系统内环设计为姿态控制,外环设计为位置控制。实验结果表明,所设计的控制算法能够有效的抑制干扰,提高系统的控制精度和鲁棒性。
In the study on the optimization of the control system of four - rotor aircraft, four - rotor aircraft is often subject to external disturbance and prone to poor anti - interference ability and low control accuracy. Aiming at the a- bove problems, an adaptive backstepping control algorithm is proposed to design the position controller. The control method based on backstepping, combined with the adaptive principle and the integral link, was introduced. Accord- ing to the idea of switching control, adjustment strip - shaped region was set to determine whether join the integrator. Backstepping robust adaptive control algorithm was used to control the attitude. The four - rotor aircraft attitude con- trol system was designed to control the inner and outer rings were designed to position control. The Experimental re- sults show that the designed control algorithm can effectively restrain interference, and improve the system control precision and robustness,
