After analyzing compensation conditions for 3 - axis stabilization to overcome disturbance from ship surge, sway and yaw, two control strategies - feed - forward compensation and closed - loop feedback compensation - are given. these two strategies are applied to antenna stabilized tracking system with good performance. intelligent pid is used in closed - loop feedback compensation to get high tracking precision and rapid response
重點分析了天線穩定控制系統的三軸補償條件,提出了穩定系統抑止載體擾動的控制策略:對于橫滾和俯仰系統採用前饋補償的控制策略;對于方位系統,在以步進電機為驅動元件的特定條件下,研究了變控制周期的閉環反饋策略,同時成功將智能pid演算法應用於實際系統,提高了系統的跟蹤精度和響應快速性。This method makes it possible for investigating the unsteady nonlinear potential flow in a complicated environment with higher efficiency. the aerodynamic forces of a wing in couple motion of heave and pitch with ground effect are analyzed in detail based on the numerical result. it is shown that a thrust force exists when the wing is in heave motion
深入系統地分析了存在表面效應時機翼運動規律和氣動力之間的關系,研究結果表明,機翼升沉運動產生的推力與升沉速度幅值的平方成比例,推力和推進效率和振蕩頻率成反比;機翼的俯仰運動可以調節推力和推進效率,但是單純的俯仰運動不會產生推力。
