摘要: 基于欠驱动、强耦合、非线性小型四旋翼飞行器模型的位置和姿态控制问题,提出一种双闭环积分滑模控制系统。内环为姿态环,采用积分滑模控制,外环为位置环,采用PID控制。由于飞行器的欠驱动性,俯仰角和滚转角的参考值由外环控制器给出。采用李雅普诺夫稳定理论验证了控制器的稳定性,根据Matlab仿真验证了所设计系统的有效性并分析验证了积分滑模控制器的控制特点。

Abstract: A double closed-loop control system based on integral sliding mode was proposed to solve the problems of position and attitude control of an under-actuated, nonlinear coupling quadrotor model. An integral sliding mode control method was applied in the inner loop attitude control and a PID controller was designed in the outer loop position control. Due to the under-actuated property of the quadrotor model, desired pitch and roll angles were given by outer loop controller. The stability of the designed control system was proved by Lyapunov stability theorem. Simulation results on Matlab show the effectiveness of the proposed control system and the characteristics of integral sliding mode control.

Key words: quadrotor, integral sliding mode, attitude control, position control, PID control, under- actuated system
