Model-Based Optimal Control of Polymeric Composite Cure in Autoclave System

A partial differential equation model predictive control strategy: application to autoclave composite processing

Cure Cycle Optimization of Rapidly Cured Out-Of-Autoclave Composites

Out-of-autoclave prepreg typically needs a long cure cycle to guarantee good properties as the result of low processing pressure applied. It is essential to reduce the manufacturing time, achieve real cost reduction, and take full advantage of out-of-autoclave process. The focus of this paper is to reduce the cure cycle time and production cost while maintaining high laminate quality. A rapidly...

Simplified Model-based Optimal Control of Vav Air-conditioning System

A simplified optimization process (SOP) for determining set points is proposed and evaluated using the monitoring data and model of an existing VAV system. Controller set points, such as supply air temperature, supply duct static pressure, and chilled water supply temperature, are determined by this proposed SOP in order to minimize energy use while respecting thermal comfort. Zone air temperat...

Crop Model-Based Greenhouse Optimal Control System: Survey and Perspectives

A survey is presented of the developments in scientific literature on the greenhouse optimal control. The related problems to optimal control were discussed, and the schematic diagram of optimal control system, combined crop models and optimization algorithm were covered focusing on issues such as: model simplification and validation, definition of objective function, input or output constraint...

Optimal Torque Control of PMSG-based Stand-Alone Wind Turbine with Energy Storage System

In this paper optimal torque control (OTC) of stand-alone variable-speed small-scale wind turbine equipped with a permanent magnet synchronous generator and a switch- mode rectifier is presented. It is shown that with OTC method in standalone configuration, power coefficient could be reached to its maximum possible value, i.e. 0.48. An appropriate control algorithm based on turbine characterist...
