中文说明： IMC-PID是利用内模控制原理来对PID参数进行计算，代码里有很完整的注释和解释，预报误差法参数辨识-松弛的思想，感应双馈发电机系统的仿真，解耦，恢复原信号，实现用SDRAM运行nios，同时用SRAM保存摄像头数据。
English Description：
IMC-PID is the use of the internal model control theory to calculate the PID parameters, code has very complete the comment and explanation, prediction error method of parameter identification-flabby thinking, simulation of induction doubly-fed generator systems, decoupling of signal recovery, using SDRAM running Nios and store camera data in SRAM.
