中文说明：利用matlab/Simulink建立了双连杆小车的LQR控制器。在初始条件为x1_init，x1_dot_init，x2_init，x2_dot_init，…x6_init，x6_dot_init小于0.05 rad（或0.05 rad/s）的情况下，控制器可以在至少20秒后对系统进行平衡，这是我自己的硕士毕业论文的序言
English Description：
I use matlab/Simulink to create a LQR controller for a two-link cart. With the initial condition as x1_init,x1_dot_init,x2_init, x2_dot_init, .....x6_init, x6_dot_init is smaller then 0.05 rad (or 0.05 rad/s), the controller can balancing the system after least then 20s. It is my own prolect for final thesis of master
