We report a low-cost, high-performance analog electronic temperature controller based on an alternative technique to resistive bridges. The proposed device shows linearity around the working temperature, high resolution, and good transient behavior.
Assuming an imminent futuristic scenario, of 5G-and-Beyond communications networks, where different classes of autonomous unmanned aerial vehicles will use guidance, navigation and control systems relying on the network's performance, in this paper we investigate the delay and packet loss effects which may lead to closed-loop stability margins degradation of such aerial vehicles, causing accidents. The use of state observers can minimize these adverse effects by allowing these control systems to receive estimated data whenever sensor data is delayed or lost. In this sense, we propose the assessment of a Smith predictor-based selftuning control applied to a 6-DOF model of a network-controlled quadrotor. The investigation is focused on Proportional-Integral-Derivative control due to its solid acceptance as a trustworthy industrial technique. Simulations and robustness indices indicates that the investigated control approach can guarantee the robust stability of such aerial systems within the considered scenario.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
