摘　　要：详细研究了无尾飞机横侧向系统的稳定性,并针对该无人机横侧向控制系统,运用经典的控制方法,通过优化而自动调节控制律参数的一种时域方法设计控制律,优化算法采用序列二次规划方法。仿真结果表明运用该方法所设计出的控制律结果满足飞行品质要求,提高了传统的人工调节控制器参数的效率,同时该方法也可以用于其它被控对象的控制律设计。Aim. Recently higher requirments on the flying quality of the lateral control system of a tailless aircraft make the traditional approach to its parameter-optimal design increasingly less applicable.We now present a more applicable approach.In the full paper,we explain our approach and its simulation in some detail.In this abstract,we just add some pertinent remarks to listing the four topics of explanation.The first topic is： the analysis of the natural stability of a tailless aircraft.The second topic is： the design of the control law for lateral control system.The third topic is： SQP（Sequential Quadratic Programming） algorithm and its implementation.In the third topic,we discuss how,keeping in mind our needs,to execute suitably the details required by the three steps of SQP algorithm in the Matlab toolbox.The fourth topic is： parameter-optimal design and its simulation.In topic four,we first discuss the four steps of design;essentially the parameter-optimal design achieves the search for optimal parameters through an iteration process which is kept convergent.Also in topic four,we summarize the simulation results in two figures and one table in the full paper;these results show preliminarily that,compared with the traditional approach,our approach is better in two respects：（1） for one design state,it can give good optimal results almost automaticaly,thus saving much time;（2） when many design states are considered,as is now increasingly the case,the saving in time is much more.
