This work investigates the use of new actuation methods in capacitive shunt micro switches. We formulate the coupled electromechanical problem by taking into account the fringing effects and nonlinearities due to mid-plane stretching. Static analysis is undertaken using the Differential Quadrature Method (DQM) to obtain the pull in voltage which is...

In this paper, the DC-link voltage control of DC-DC boost converter-inverter system is proposed. The mathematical model is developed from four different sub-circuits that depended on the switch positions. The developed differential equations are combined to develop the dynamic model. Transfer function is generated from the switched function model....

FIDELIO (Fully Interregional Dynamic Econometric Long-term Input-Output) is a multi-sectoral model developed by the unit B.5 of the Directorate General Joint Research Centre (JRC) — the circular economy and industrial leadership unit. Compared to neoclassical CGE models — which assume that the perfect flexibility of prices and quantities ensures th...

European Union legislation sets mandatory emission and fuel consumption reduction targets for new vehicles and therefore economy remains a key challenge for automotive engineers. Optimizing the transmission shift schedule for an automatic transmission with double clutch is an important part of improving fuel economy. Using simulation and optimizati...

This paper presents modeling and model predictive control (MPC) of a hybrid cable-driven robot (HCDR). First of all, a whole-body model is developed for the HCDR. To simplify the system modeling in practical applications, a decoupled model is then proposed to divide the whole system into two subsystems: in-plane and out-plane systems, where the for...

Harvesting energy from rotational motion for powering low-power electrical devices is attracting increasing research interest in recent years. In this paper, a magnetic-coupled buckled beam piezoelectric rotation energy harvester (MBBP-REH) with bistable and frequency up-conversion is presented to harvest low speed rotational energy with a broadban...
