【摘要】 通过对无人驾驶自转旋翼机纵向通道的数学模型和机理分析,研究了旋翼机的高度控制策略,提出了一种以俯仰姿态控制和发动机推力控制为基本控制回路的高度控制方法,实现了自转旋翼机的定高控制和高度跟随控制。通过仿真验证,所提出的无人驾驶自转旋翼机高度控制方法具有较好的高度跟随特性。更多还原

【Abstract】 A height control measure for unmanned gyroplanes is invested.Based on modeling of the gyroplane,a control strategy for height loop of the plane is presented that the pitch angle and thrust are used as control variables so that height error is decreased obviously.The results of simulation of the height control system also demonstrate that gyroplane has well performance to meet the demands of height response.更多还原
