Figure 4From: Adaptive fault estimation for T-S fuzzy systems with unmeasurable premise variablesActuator fault parameter \(\theta_{2}(t)\) and its estimation. The red line denotes state \(\theta_{2}(t)\) while the blue line denotes its estimation. The lower part is the result obtained using method proposed in this paper, while the upper part is the result obtained using method proposed in [11]Back to article page
