This paper investigates the robust H∞ faulttolerant controller design under actuator failure for a class of the stochastic Markov jump timedelay systems with parameter uncertainties. The existence condition of the state feedback robust H∞ faulttolerant controller with actuator failure is presented. The robust H∞ faulttolerant control algorithm is derived in the form of linear matrix inequality via the Lyapunov stability theory. The proposed control does not need to estimate the boundary value of an actuator fault, nor does it depend on fault detection and diagnostic devices. By solving the linear matrix inequality, a robust faulttolerant controller, which makes the closedloop system asymptotically stable and whose H∞ performance is restricted by a given bound, is designed such that its structure is comparably simpler and does not require a large number of calculations. The designed controller is applied to a UAV illustrative example. The numerical results and computer simulation demonstrate the effectiveness of the proposed fault tolerant control.

“…There are a number of inputs that impact the quality of the lamination process [9]: temperature, duration, pressure/vacuum time. As according to us, temperature and duration of the process have the greatest impact on the quality of encapsulation, we decided to measure the temperature from the edge of the module during the real manufacturing lamination cycle.…”

One of the most important steps during manufacturing of solar modules is lamination. This paper focuses on monitoring of behavior of used encapsulant Ethylene/Vinyl-Acetate (EVA) and impact on overall quality of module during lamination. Monitoring is performed by employing external thermocouple sensor inside the lamination chamber as well as by. Real-time analysis of the results helps to predict the quality of final product in terms of ensuring lamination quality in real time and provides possibility to tune the process during manufacturing cycle to achieve the best result of encapsulant cross-linking.
