：VB与Matlab混合编程方法，通过建立VB与Matlab间的ActiveX连接，实现VB应用程序中调用Matlab， 建立与Matlab ActiveX服务器的连接。该方法通过利用ActiveX技术、应用DDE与Matlab通讯、使用MatrixVB、 生成执行文件、编译动态链接库等步骤实现(: VB and Matlab programming mix, VB and Matlab through the establishment of connection between the ActiveX, VB application, call the realization of Matlab, the establishment and Matlab ActiveX server. The method is through the use of ActiveX technologies, applications and Matlab DDE communication, the use of MatrixVB, generated executable file, compiled dynamic link libraries and other steps to achieve)

Incremental Conductance: In the incremental conductance algorithm, we find the derivative of PV output power with respect to output voltage. The dP/dV is evaluated and the algorithm keeps checking this value and changes the duty cycle such that dP/dV=- I/V = 0. This is the point at which maximum power is transferred. If dP/dV is greater than zero, it means the PV is operating to the left of the MPP. If dP/dV is less than zero, it means the PV is operating to the right of the MPP. This method holds an advantage over the perturb and observe method since it is fast and does not oscillate around MPP. However, the method could experience instability due the involvement of the derivative.
