attitudecontrolofaircraft
- 本文首先建立了航天器姿态动力学及运动学方程，该方程具有较强的非线性特性。通过将状态耦合部分作系统干扰项的处理，使原来的非线性模型转化为线性模型加非线性干扰的形式，从而得到了更加简单明了的姿态控制系统的表达式。 在应用滑模变结构原理对系统进行控制器设计时，首先通过二次型最优法求出了最优滑动面，在此基础上，利用自适应滑模控制原理，设计出了合适的系统控制律。 最后，运用所设计的姿态控制系统对某航天器进行数值仿真，并对仿真结果进行了分析。仿真结果很好地体现出所设计的变结构控制器的优点，并成功地
lcx_LINUX-mlock
- LINUX系统调用mlock的代码分析,在LINUX中，每一个用户进程都可以访问4GB的线性虚拟内存空间。其中从0到3GB的虚拟内存地址是用户空间，用户进程可以直接对其进行访问。从3GB到4GB的虚拟内存地址为核心空间，存放仅供核心态访问的代码和数据，用户进程不可访问。当用户进程通过中断或系统调用对其访问时，就会触发处理器的特权级转换（从处理器的特权级3切换到特权级0），即从操作系统的用户态切换到核心态。-Linux system call mlock code analysis, LINUX,
