| 1 | Finite Time Convergent Wavelet Neural Network Sliding Mode Control Guidance Law with Impact Angle Constraint显示文摘This paper presents a novel guidance law to intercept non-maneuvering targets with impact angle and lateral acceleration command constraints. Firstly, we formulate the impact angle control to track the desired line-of-sight(LOS) angle, which is achieved by selecting the missile s lateral acceleration to enforce the sliding mode on a sliding surface at impact time. Secondly, we use the Lyapunov stability theory to prove the stability and finite time convergence of the proposed nonlinear sliding surface. Thirdly, we introduce the wavelet neural network(WNN) to adaptively update the additional control command and reduce the high-frequency chattering of sliding mode control(SMC). The proposed guidance law, denoted WNNSMC guidance law with impact angle constraint,combines the SMC methodology with WNN to improve the robustness and reduce the chattering of the system. Finally, numerical simulations are performed to demonstrate the validity and effectiveness of the WNNSMC guidance law. | Qing-Chun Li Wen-Sheng Zhang Gang Han Ying-Hua Zhang | 2015 | International Journal of Automation and computing2015，12，6： | 10 |
| 2 | 推力矢量拦截弹制导控制一体化设计显示文摘针对采用推力矢量控制的拦截弹,首先给出了推力矢量和气动力的归一化设计方法,通过引入等效舵偏角的概念,将多控制输入问题转化为单控制输入问题,并进行求解,设计了推力矢量偏心和气动舵偏转的控制分配策略,给出了气动舵偏转角及推力矢量偏心角的数学表达式,解决了多控制量之间相互争斗的问题。在此基础上,通过模型标准化,采用Backstepping方法(反步法),借助Lyapunov再设计工具,对导弹制导与控制系统进行一体化设计,得到了俯仰平面内的制导控制律。仿真结果表明,和常规制导与控制方法分别设计相比,采用该制导控制一体化设计方法能够使拦截弹有效拦截机动目标,并且导弹的姿态和执行机构偏角的变化也更加平稳。 | 惠耀洛 南英 邹杰 | 2015 | 弹道学报2015，27，4： | 2 |
