i am working on fault detection of a suspension system using fuzzy. problem is i have to convert my model (differential equations) into space space form. but in which form i can convert it ? need any paper or stuff that can help me understand how i can do it all. i want to implement multiple fuzzy models for fault detection.
Dear Noman,
First of response for the initial part ie the conversion of the model described by differential equations to the state space equations, in fact it has both SISO and MIMO.
- SISO model is treated simply by making assumptions of choice of states of the model preferably having a particular canonical form; it necessarily result in the determination of quadriplet (A, B, C, D).
- For the MIMO case the thing is developed and it uses algorithms such as Guilbert algorithm or Ho-Kalman algorithm...
Now concerning the implementation of multiple fuzzy models for fault detection, in fact fuzzy logic-based diagnostic is advantageous since it allows the incorporation of a-priori knowledge and lets the user understand the inference of the system.
In these two parts you find enclosed the attached references.
