Detection Filter Builder
Contents
Introduction
GUI to assist in fault detection, isolation and reconfiguration (FDIR). This will help you construct a detection filter step-by-step. It uses multiple plug-ins to walk you through the process all the way to a simulation of your newly built filter. In the end, this will create a detection filter data structure. It requires 5 steps:
1. State Space tab
- Select State Space .mat File: This should be a mat file that contains a state space data structure... i.e. a variable x with field elements
x.a
x.b
x.c
x.dcorrelating to the 4 state space coefficients.
OR
- Select a right hand side function that returns a state space data structure or a state space model in the state space structure form. The RHS function cannot have any arguments. If you have a nonlinear function you must pre-linearized the system and put it into state space form.
2. Reduce Order tab
You then click the Reduce order tab if you want to reduce the order of the system. Do this only after you have performed one of the above.
3. Normalize tab
Click the normalize tab to normalize the states. Normalization can make it easier to interpret the residuals. Do this only after you have performed the above.
4. Compute Gains tab
The Compute Gains tab actually computes the detection filter gains. Click this after you have performed the above.
5. Simulate tab
The Simulate tab simulates the system. Click this after you have performed all of the above.
