matlab下的卡尔曼滤波器！外推方程、协方差外推公式、滤波协方差方程！(Kalman filter under matlab! Extrapolation equation, covariance extrapolation formula, the filter covariance equations!)

File 1: THIS CODE IS USED TO DRAW THE PUMP CURVES AT DIFFERENT PUMP SPEED 1: PUMP CURVE 2: EFFICIENCY CURVE 3: BREAK HORSEPOWER CURVE 4: KW-INPUT CURVE File 2: THIS CODE IS FOR APPLYING THE WAY OF CALCULATING THE EFFICIENCY, POWER AND KW-INPUT FOR VARIABLE SPEED PUMP AT A GIVEN DESIRED HEAD AND DESIRED FLOW AS SHOWN IN THE PAPER TITLED: " how to calculate the pump efficiency and power for variable speed pump" File 3: this code is to correct the use of affinity law by shifting the curve to intersect with the system-curve at the desired flow as shown in the paper titled: "The Correct Method of Calculating Energy Savings to Justify Adjustable-Frequency Drives on Pumps"

matlab仿真模型，空间矢量控制模型，可以当作毕业设计内容使用。(matlab simulation model, space vector control model can be used as a graduation project content.)

说明：  扩展卡尔曼滤波 用于信号处理, 初学者可是直接仿真使用(Extended kalman filter for signal processing, beginners but direct simulation use)

Simulink下的脉冲激励模块。可以设置激励值和时间。(Simulink, the pulse excitation module. You can set the value and timing of incentive.)

code based on filter banks
