Observer Design for Cyber-Physical Systems With State Delay and Sparse Sensor Attacks by Man Zhang, Chong Lin, Yadong Li, Bing Chen

“…In addition, based on the generalization of the classical Krasovskii Stability Theorem for stability analysis of time-delay systems, a Lyapunov-Krasovskii functional is chosen and a sufficient condition for the existence of the observer together with its design method is determined. The designed observer overcomes the difficulties caused by state delay and sensor attacks, and has good performance in secure estimation. …”

Robust Fault Detection of Linear Uncertain Time-Delay Systems Using Unknown Input Observers by Saeed Ahmadizadeh, Jafar Zarei, Hamid Reza Karimi

“…The design procedure is carried out based on the model matching approach which minimizes the difference between generated residuals by the optimal observer and those by the designed observer in the presence of uncertainties. The optimal observer is designed for the ideal system and works so that the fault effect is maximized while the exogenous disturbances and noise effects are minimized. …”

Active disturbance rejection control of temperature of thermoelectric module by Jorge Luis Barahona-Avalos, José Antonio Juárez-Abad, G. S. Galván-Cruz, Jesús Linares-Flores

“…Said disturbance is estimated by means of a generalized proportional integral type observer, which in combination with the controller allows to regulate the temperature on the cold face of the thermoelectric module to a desired constant value. The designed observer simultaneously estimates the step-down converter output voltage and the exogenous disturbance in an on-line cancellation scheme, known as active disturbance rejection control. …”
