Quadrature amplitude modulation is a method of combining two amplitude-modulated signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation in digital systems, especially in wireless applications

卡尔曼滤波仿真算法！！！经典的哦！！！！！！！！(Kalman filter simulation algorithm. ! !)

基于前馈补偿的PID控制算法。可以通过设置M参数查看控制效果（M=2时误差平稳且接近0）。(Feedforward compensation based on the PID control algorithm. You can view the control parameters by setting the effect of M (M = 2 when the error is stable and close to 0).)
