研究飞艇高空定点优化控制问题,针对飞艇在高空时空气舵面操纵不足、舵效控制力低,为解决上述问题,提出了采用气动力舵面和偏转螺旋桨复合控制的操纵模式对高空飞艇的姿态进行控制的方法。首先给出了采用气动力和螺旋桨拉力矢量组合控制的高空飞艇横侧向数学模型,把气动力舵面和偏转螺旋桨复合控制看作一个双输入单输出系统,采用线性模型跟随方法设计了姿态控制系统,使控制系统的性能尽可能地跟随给定的理想参考模型系统的性能。通过仿真表明偏转螺旋桨操纵控制可以有效弥补空气舵面效率的不足,所设计控制系统具有良好的动态品质,并验证了方案的可行性和方法的有效性。
In order to solve the above problems, aiming at the problem that the airship can not control the air-surface at high altitudes and the rudder-effect control is low, this paper proposes a control mode of airship with a combination of pneumatic rudder and deflection propeller The method of control. First of all, a lateral lateral math model of airship with aerodynamic force and propeller pull force vector control is given. Combined control of aerodynamic rudder face and deflection propeller is regarded as a two-input single-output system. The attitude control System that allows the performance of the control system to follow as closely as possible the performance of a given ideal reference model system. Simulation results show that the control of deflection propeller can effectively make up for the lack of efficiency of the air rudder surface. The designed control system has good dynamic quality and the feasibility of the scheme and the effectiveness of the method are verified.
