| Abstract: | In order to solve the problem of sensor fault detection and isolation for under-measurement system,firstly,we resort the output equation to convert sensor fault difficult problem into state disturbance of the dynamic system with least-squares solution and basic solution series.Then,a residual generator is used to fault detection and isolation is designed.In addition,we put forward the method for solving unknown parameters in it.Finally,simulations results demonstrate that the method of basic solution series... |
