State and multiplicative sensor fault estimation for nonlinear systems
2013 Conference on Control and Fault-Tolerant Systems (SysTol)
This paper addresses the state and sensor fault estimation for nonlinear systems represented by Takagi-Sugeno (T-S) models. The considered faults are time-varying and with multiplicative effect on the sensor output signals. The proposed estimation procedure is based firstly on the sector nonlinearity approach using the convex polytopic transformation where the original system is equivalently rewritten as a Takagi-Sugeno system with unmeasurable premise variables and, secondly on the design ofdoi:10.1109/systol.2013.6693898 fatcat:sqriebq7jzfvtpsu56w5g6wxni
