摘要

为了解决四旋翼教育平台控制中的输入延迟问题,对滑模控制方法进行了改进。该方案使用一个预测器来补偿输入控制的延迟效应,例如在地面站计算控制律时可能出现的延迟效应。用李雅普诺夫稳定性分析方法证明了存在扰动和输入延迟时指数闭环的稳定性。通过数值仿真验证了控制律的有效性。

Quad-rotor orientation control by predictor based sliding mode control
A Sliding Mode Control (SMC) is modified in order to address the input delay in the control of quadrotor educational platform. The proposed scheme uses a predictor that compensates the delay effect on the input control which can appear for example when the control law is computed in a ground station. A Lyapunov stability analysis is presented to prove the exponential closed-loop stability in presence of perturbations and input delay. The control law is tested with numerical simulations to evaluate the expected results.
