中文说明：控制质量 - 弹簧 - 阻尼器通过LQR和LQR最优控制系统的方法在这个仿真代码质量弹簧阻尼器的简单和众所周知的机械系统进行了研究。控制这种不稳定的振荡系统的稳定是一个巨大的挑战，以便需要一个完整的电源控制器。稳定系统是由被称为LQR（线性二次型调节器）的最佳完善的控制方式设计的。这种最优控制技术将噪音或未知干扰的存在切换到LQG（线性二次型高斯法规）。
English Description：
controlling a mass- spring- damper system via LQR and LQG optimal control approachin this simulation code a simple and well- known mechanical system of mass-spring- damper has been studied. Control and stabilization of such an unstable oscillatingsystem is a great challenge so a power full controller is needed. The stabilizersystem is designed via an optimal wellestablished control approach known as LQR (Linear Quadratic Regulation). thisoptimal control technique will switched to LQG (Linear Quadratic GaussianRegulation )in presence of noise or unknown disturbances.
