Sunsoo Kim, Vedang Deshpande, Raktim Bhattacharya

摘要:

比例-积分-微分(PID)算法是无人机控制器设计中最常用的算法。然而,调整PID增益是一项重要的任务。已经开发了许多方法来调整无人机系统的PID增益。然而,这些方法不处理风干扰,这是一个主要关注的小型无人机。在本文中,我们提出了一种新的方法来确定优化的PID增益的H2最优控制框架,实现了改进的风扰动抑制。所提出的方法比较了经典的PID控制规律与H2最优控制器,以确定H2最优PID增益,并涉及解决一个凸优化问题。所提出的控制器进行了测试,在两种情况下,即,垂直速度控制,和垂直位置控制。将结果与现有的基于LQR的PID整定方法进行了比较。

英文摘要:

Proportional-Integral-Derivative (PID) scheme is the most commonly used algorithm for designing the controllers for unmanned aerial vehicles (UAVs). However, tuning PID gains is a non trivial task. A number of methods have been developed for tuning the PID gains for UAV systems. However, these methods do not handle wind disturbances, which is a major concern for small UAVs. In this paper, we propose a new method for determining optimized PID gains in the H2 optimal control framework, which achieves improved wind disturbance rejection. The proposed method compares the classical PID control law with the H2 optimal controller to determine the H2 optimal PID gains, and involves solving a convex optimization problem. The proposed controller is tested in two scenarios, namely, vertical velocity control, and vertical position control. The results are compared with the existing LQR based PID tuning method.
