Correctness and validity of arithmetic are analyzed. With flight dynamics  the roll-loop mathematic model and reference model are established. Sliding hyperplane is deduced based on model reference sliding mode variable structure theory. Combing with reaching law  control law is derived  and stability of roll-loop is analyzed. Chattering of aileron instructions is alleviate by using boundary layer approach. Digital flying simulation result shows that variable structure control arithmetic realized roll stabilization control  the roll angle is less than 5.3 under powered flight  and that of unpowered flight is less than 0.5  respectively. The command fin angle is less than 1.5. High frequency chattering of fin command nearby the minimum velocity was trailed off by chattering reduction arithmetic. The sliding mode control arithmetic show good performance when aerodynamic coefficients varies 20%. The control arithmetic is easy to be implemented for its simplicity. 2011 IEEE.   基于规则的软件过程事务模型 期刊论文  OAI收割 软件学报, 2002, 卷号: 13, 期号: 1, 页码: 24-32 沈备军; 陈诚; 居德华   |  收藏  |  浏览/下载：8/0  |  提交时间：2011/07/29 软件过程  软件过程事务  扩充事务模型  软件过程支持环境  正确性规则  software process  software process transaction  extended transaction model  PSEE  correctness criteria  正确性规则  软件过程  高级事务模型  Transaction Model  software process transaction  cooperative transaction  correctness criteria  transaction
