    Developing MIMO Filter?

    I solved the problem. It was rather quite easy. Instead ov inverting the transfer function for creating an inverse filter impuls response I had to inverse the complete complex matrix containing the 9 transfer functions. It works - when filtering first my input with this matrix I receive my...

    Developing MIMO Filter?

    OK it's a real structure. My system is a steel-bar with a mounted steering-wheel. Aim is to simulate vibration-signals on a steering wheel. I've got one shaker connected to the system over a fork-joint to generate rotational movement. I've got two shakers mounted vertically and horizontally...

    Developing MIMO Filter?

    Yes and No I'm applying force in 3 dimensions simultaneously. I'm measuring the 3 dimesions on the system output. My ideal case : I receive in x-Dimension only the x-force in y-Dim. only the y-force and so one. I measure the transfer function - build a inverse FIR-filter and convolute it...

    Developing MIMO Filter?

    Hello, I've got a system with 3-dimensional-vibration input (3 Shaker) and I want to measure the vibration at 3 different output-points. I want to filter my system with an inverse FIR-Filter to suppress system attenuation ant to get the desired vibration for the desired direction. Well, this...

    Problems with inverse Transfer Function Filter

    Hello, I'm working on a inverse-TF-filter for compensating attenuation of my system. Description of the System is: Labview(sweepsignal(mag 1, 200-20Hz, 30sec):Fileoutput) - Amplifier - Shaker(B&K) - Tube - PCB-acc-Sensor - Labview(input) The idea is: measuring the Transfer Function with white...

    Transfer Function Filter

    Hello, I like to develop a software-filter for compensating the frequency attenuation of an elctrodynamical-shaker. My idea is to measure the transfer function from my system and to reverse it. With the reverse function and iFFT I get a response in time-domain. Then I do a convolution with...
