In an engine control device, a saturated water vapor pressure Ps is calculated from an intake temperature detected by an intake air temperature sensor. A water vapor partial pressure is worked out from the saturated water vapor pressure and humidity detected by a humidity sensor. A specific humidity q and a molar fraction are worked out from the water vapor partial pressure and an atmospheric pressure detected by an atmospheric pressure sensor. A moist air amount is calculated from an intake air amount detected by an AFS on the basis of the molar fraction, and a dry air amount is calculated from this moist air amount on the basis of the specific humidity. A fuel injection amount, an ignition timing, and a target throttle opening are then calculated on the basis of various operation information, using the moist air amount, the dry air amount, and the specific humidity.

An in-vehicle engine control apparatus allowing split injection frequency or split injection of fuel while preventing a driving switch element for fuel injecting electromagnetic coils and a boosting switch element for generating a boosted high voltage from being overheated. An operation control circuit portion has reference data of measured environmental temperature vs allowable engine rotational speed with a selected value of the split injection frequency being a parameter, and determines the selected value having, as an upper limit, a split injection frequency which makes the internal temperature of the boosting switch element or a rapidly exciting switch element a predetermined allowable limit value in association with the present environmental temperature detected by an average environmental temperature detection element in a case and the present engine rotational speed detected by an engine rotation sensor.

The objective of the present invention is to provide a controller for a supercharger-equipped internal combustion engine and a control method that can reduce man-hours for data measurement and matching, which are required to perform while the internal combustion engine and the supercharger are combined. In a controller, a target turbine flow rate for realizing a target compressor driving force is calculated; a target wastegate flow rate is calculated based on an exhaust gas flow rate and the target turbine flow rate; a target turbine-upstream pressure is calculated based on a target before/after-turbine pressure ratio for realizing the target compressor driving force and a turbine-downstream pressure; a target gate effective opening area is calculated based on the target wastegate flow rate, the target before/after-turbine pressure ratio, and the target turbine-upstream pressure; then, a gate valve control value is calculated.

A controller, for a supercharger-equipped internal combustion engine, that can improve the feedback response of compressor driving force is provided. In a controller, inertial force produced by an inertial moment of a supercharger is calculated, based on a real rotation speed of the supercharger; then, driving force feedback control is implemented in which a gate valve control value, which is a control value for a gate valve actuator, is changed so that an addition value obtained by adding the inertial force to the real compressor driving force approaches a target compressor driving force.

A method for transforms input signals, by first defining a model for transforming the input signals, wherein the model is specified by constraints and a set of model parameters. An iterative inference procedure is derived from the model and the set of model parameters and unfolded into a set of layers, wherein there is one layer for each iteration of the procedure, and wherein a same set of network parameters is used by all layers. A neural network is formed by untying the set of network parameters such that there is one set of network parameters for each layer and each set of network parameters is separately maintainable and separately applicable to the corresponding layer. The neural network is trained to obtain a trained neural network, and then input signals are transformed using the trained neural network to obtain output signals.

In order to unlock the full potential of Europes offshore resources, network infrastructure is urgently required, linking off-shore wind parks and on-shore grids in different countries. HVDC technology is envisaged but the deployment of meshed HVDC offshore grids is currently hindered by the high cost of converter technology, lack of experience with protection systems and fault clearance components and immature international regulations and financial instruments. PROMOTioN will overcome these barriers by development and demonstration of three key technologies, a regulatory and financial framework and an offshore grid deployment plan for 2020 and beyond. A first key technology is presented by Diode Rectifier offshore converter. This concept is ground breaking as it challenges the need for complex, bulky and expensive converters, reducing significantly investment and maintenance cost and increasing availability. A fully rated compact diode rectifier converter will be connected to an existing wind farm. The second key technology is an HVDC grid protection system which will be developed and demonstrated utilising multi-vendor methods within the full scale Multi-Terminal Test Environment. The multi-vendor approach will allow DC grid protection to become a plug-and-play solution. The third technology pathway will first time demonstrate performance of existing HVDC circuit breaker prototypes to provide confidence and demonstrate technology readiness of this crucial network component. The additional pathway will develop the international regulatory and financial framework, essential for funding, deployment and operation of meshed offshore HVDC grids. With 35 partners PROMOTioN is ambitious in its scope and advances crucial HVDC grid technologies from medium to high TRL. Consortium includes all major HVDC and wind turbine manufacturers, TSOs linked to the North Sea, offshore wind developers, leading academia and consulting companies.
