摘　　要：气动能量法在颤振主动抑制领域中的应用日趋广泛。在气动能量法的基础上,针对某型飞机,利用已有的控制面设计了颤振抑制的最优控制律,并通过一种新的计算方法寻优得到最优控制律。为验证该控制律的有效性,同时计算了无控和有控两种情况下的颤振临界速度。计算结果表明,该控制律可使某机的颤振临界速度提高10.4%。At present the aerodynamic energy method and the modern control method m the flutter suppression area are used most frequently. This paper puts forward a different method from the aerodynamic energy method but on the basis of it. Using this method in which a original control surface is used, a optimal control law of flutter suppression for an aircraft is obtained. Simulation example is given to prove that the method makes the calculation simple and the feasibility of the optimal control law. Then the v - g method is used to obtain the critical speed. The result is that the critical speed is increased by a factor of 10. 4%. So the performance of the control law has been validated.
