In this paper, a dual-electrode gas switch triggered by ejected plasma is proposed to ensure the switch to be triggered reliably under extremely low switching coefficient. The switch has the configuration of dual electrodes, in one of which a microincentive chamber is embedded to develop ejected plasma into the switch gap, leading to the breakdown of the switch. Both the features of ejected plasma...
This paper evaluates geometric programming as a solver to optimize mechatronic system design in a holistic manner to aid early design decisions. Mechatronic systems design optimization requires complex and often non-convex functions as design objectives and constraints. Currently the solutions are primarily based on randomized search methods, e.g., genetic algorithms, and they are time-consuming....
Open-loop unstable systems with time delay are difficult to control using routine control methods. To solve this problem, an improved internal model control scheme, which adds a PD controller to traditional IMC structure, is proposed. Set point tracking performance and robustness can be designed independently. The tuning formula of PD controller is confirmed by a new performance index function. Fuzzy...
