飞行仿真转台伺服系统滑模控制器设计

Design of sliding controller for flight simulator servo system

针对转台位置伺服系统中存在的非线性摩擦环节,设计一种补偿摩擦的滑模控制器。该控制器把摩擦作为系统的有界扰动,利用滑模控制,在仅知道摩擦力矩上界的情况下,对摩擦进行补偿。仿真结果表明,该控制器有效地抑制摩擦力矩的影响,实现高精度的位置跟踪,鲁棒性强。

In this paper, we present a sliding control method to compensate the friction in the flight simulator servo system. The friction torque is treated as a bounded disturbance and rejected by the variable structure controller. The stability condition for the controller design is also provided in the paper. Simulation results demonstrate the effectiveness of the proposed method.
