Address, 2010 -7-14 19:54
Matlab expert to help! Currently, I have several sets of data: time, input data, the corresponding output data. My question is, how to build input-output transfer function? ? What method, or kit it? Can an example? Is very important to ah, make sure to help me master this busy! Some details of that very grateful! ! Asked by: scorpion text - four best answer
A system identification problem, the problem, you can try to complete deconv function, this function is deconvolution, which is solved through the input-output system, or by solving the input-output system 2 the best way is using neural network modeling. Several sets of input data to output data as input and output. Train the neural network, the demand factor is the weight! Identification of the completion of its transfer function. Of these, good luck! 1

transfer function input output

Here a mathematical model based on electrical systems -> structure -> the signal flow diagram -> Transfer Function -> Simulation -> theoretical results and simulation results of the comparison. Analysis.
(1) mathematical modeling
Firstly a system schematic, analyze. To find out the status of the system (energy storage components, nothing more than capacitors and inductors); input and output;
Under normal circumstances can be listed under the KVL KCL equation of state; according to the schematic and list the output equation.
With the state and output equations, even built a mathematical model.
(2) According to the mathematical model of the system structure to draw
Note: The structure of a system and signal flow diagram is not unique, but among them are equivalent.
Give the model state variables, input and output of each to a node. Order from left to right connection for each node (line, there are gain).
Discrete dynamic system with differential, continuous dynamic systems integrator and differentiator.
This will complete the system structure
(3) The structure of the picture signal flow chart of the system
Differentiator corresponding to 1 / Z, corresponding to the integrator 1 / S, the corresponding differentiator S, the structure of the state point to find out, respectively, and point to add, input, output point, the state point distribution node. According to the forward or feedback, from left to right draw. Will complete the signal flow chart.
(4) According to the signal flow graph and Mason rule to determine the system's input-output transfer function
For single-input single-output system, if the signal flow diagram with system structure or the rules so you can get under the Mason system transfer function. Need to introduce a few concepts before once again:
Source node: the input nodes; well node: output contacts;
Forward path: input to output without loop path. Path gain is the product of each branch.
Circle: The signal for the beginning and end of the path of the same node. Path gain is the product of a slip.
Mason rules: First, the system first, before calculating the number of channels; (the specific formula, can not write here);
Each unit is always calculated after the addition and to get the system transfer function.
(5) simulation
Simulation process is: first write the state function (including input); in writing the main program (with a certain algorithm to calculate the equation of state functions); drawing can be
(6) calculated
Calculation is through input and system transfer function (that is, the system impulse response) to calculate the system output.

what is a transfer function - is it just a relation between output/input or is it the 'time response' relation between the output & input.
