基于kalman滤波的最小二乘法的matlab程序，仅供参考(Kalman filter based on least squares matlab program for reference only)

说明：  生成PI的一个小程序 可以精确掉小数点后几百位。 (PI generated a small program can accurately swap places after the decimal point a few hundred.)

ask qpsk bpsk的调制解调程序 希望对 大家有所帮助(ask qpsk bpsk of modulation and demodulation process hope to help)

The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
