用C语言实现的傅里叶计算，硬件平台为TMS320F2812(Using C language implementation of the Fourier calculations, the hardware platform for TMS320F2812)

说明：  传统的永磁同步电机(Permanent Magnet Synchronous Motor, PMSM)自抗扰调速 系统往往存在可调参数多且整定复杂的问题，利用滑模控制方法(Sliding Mode Control,SMC)对自抗扰控制(Active Disturbance Rejection Control, ADRC)结构进行改进，设计了PMSM 调速系统的滑模自抗扰速度控制器和电流控制器。将滑模控制方法引入自抗扰控制结构中，将自抗扰控制中的扩张状态观测器和非线性误差反馈控制律进行优化，在保留自抗扰原有抗扰性能的基础上，简化了参数整定，提高了系统的响应速度和鲁棒性，利用李雅普诺夫理论证明了控制器的稳定性。仿真结果验证了该方法的有效性。(The traditional permanent magnet synchronous motor (PMSM) ADRC system often has many adjustable parameters and complex setting. Using the sliding mode control (SMC) to improve the structure of ADRC (active disturbance rejection control, ADRC), the ADRC speed controller and current control of PMSM are designed Manufacture. The sliding mode control method is introduced into the ADRC structure. The extended state observer and the nonlinear error feedback control law are optimized. On the basis of retaining the original ADRC performance, the parameter setting is simplified and the response speed and robustness of the system are improved. The stability of the controller is proved by using Lyapunov theory. The simulation results verify the effectiveness of the method.)
