说明：  微电网下逆变器pi环控制，可以仿真出结果，波形完整(Micro grid inverter PI ring under control, you can copy the micro grid inverter under PI loop control, can the simulation results, the waveform complete real results, waveform is complete)

实序列FFT快速算法，用N点FFT计算2N点实序列的FFT，比直接进行2N点FFT运算减少一半运算量。(Real sequence FFT fast algorithm, using N-point FFT calculation 2N point real sequence of FFT, than the direct 2N-point FFT computation halved.)

Display 3D volumetric data such as MRI images dynamiclly. Click on an image to change the position.

案例为利用最有控制原理，实现对机械手转台的最优控制。运用matlab，以及simulink仿真实现。(Case for the use of the most control theory, to achieve optimal control of robotic turntable. Use matlab, simulink simulation, and implementation.)

永磁同步电机的直接转矩控制 可以学习S函数的编写 PID可以调节 想要的直接拿去(Direct torque control of permanent magnet synchronous motor can learn the writing of the S function of PID can adjust to take it directly)

Using the idea from Seam Carving for Content-Aware Image Resizing, the codes enables a selected image to resize without having distortion of important object in the image file.

用稳定边界法整定公式来求P,PI,PID的个参数，其中G是已知被校正系统的开环传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量Gc为校正器传递函数，p为系统开环极点的个数（不计重根个数，即多重根只计一个根）(With the Stable Boundary tuning formula seeking P, PI, PID' s parameters, of which G is known to be corrected and the system of open-loop transfer function, kp is proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters Gc for the corrector transfer function, p is the number of poles of open-loop system (excluding the number of multiple roots, that is a multiple root only to the root))
