Model predictive control of a multi-degree-of-freedom wave energy converter with model mismatch and prediction errors

The power captured by a wave energy converter (WEC) can be greatly increased through the use of a well-conceived wave-by-wave control strategy. Optimal strategies including Model Predictive Control (MPC) rely on a dynamic...

Investigating balancing control of a standing bipedal robot with point foot contact
Comparing with wheeled or tracked moving machines, legged robots have potential advantages, especially when considering moving on discontinuous or rough terrain. For many bipedal robots, balance in the standing position is easy...

Theoretical and experimental studies of a switched inertance hydraulic system in a four-port high speed switching valve configuration
The switched inertance hydraulic system (SIHS) is a novel high-bandwidth and energy-efficient digital device which can adjust or control flow and pressure by a means that does not rely on throttling the flow and dissipation of...

Modelling and analysis of hydraulic step-down switching converters
In this study, a steady state analysis of step-down converter systems, considering the load losses in the inertance tube and switched valve, is presented. The model describes the behaviour of the average load pressure as a...

Power-flow-based Stabilization for Adaptive Feedforward Filters in Hybrid Testing
Real-time hybrid testing is a technology which allows the coupling of simulations and component tests in order to simulate complex system dynamics. Delays and time lags caused by actuator dynamics and signal processing...

Numerical study of roll motion of a 2-D floating structure in viscous flow
In the present study, an open source CFD tool, OpenFOAM has been extended and applied to investigate roll motion of a 2-D rectangular barge induced by nonlinear regular waves in viscous flow. Comparisons among the present...

Combined steering and direct tilt control for the enhancement of narrow tilting vehicle stability
Narrow tilting vehicles offer an opportunity to reduce both traffic congestion and carbon emissions by having a small road footprint, a low weight and a small frontal area. Their narrow track requires that they tilt into corners...

Active control for multi-degree-of-freedom wave energy converters with load limiting
An active control strategy is a key component to enable efficient, safe and economical operation of a wave energy converter (WEC). Many strategies have been developed, but most studies are limited to simplified simulation models...

Passivity Control for Nonlinear Real-time Hybrid Tests

In real-time hybrid testing, systems are separated into a numerically simulated substructure and a physically tested substructure, coupled in real time using actuators and force sensors. Actuators tend to introduce spurious...

Dynamic friction modelling without drift and its application in the simulation of a valve controlled hydraulic cylinder system

The frictional modelling literature is reviewed, and it is demonstrated that unrealistic drift results when the shape coefficient is 1.0 for the LuGre and the integral friction models. Drift will not occur but other dynamic...
