SYSTEMS AND METHODS FOR TRANSIENT CONTROL OF A FREE-PISTON ENGINE

A free-piston (“FP”) engine is a type of internal combustion engine with no crankshaft, so that its piston trajectory is no longer constrained by the mechanical linkage. FP engines have a high potential in terms of energy saving given their simple structure, high modularity and high efficiency, among other attributes. One of the technical barriers that affect FP engine technology is a lack of precise piston trajectory control. For example, the presence of a transient period after a single combustion event can prevent the engine from continuous firing. The present subject matter provides a control scheme that can utilize a reference and control signal shifting technique to modify the tracking error and the control signal to reduce the transient period. 1.

An engine control system may be implemented with a multi-tier, or multi-layer software hierarchy, or modular algorithms (algorithm modules) to control injection events. In a first hierarchy, the program instructions may be executed to define time periods during which a series of fuel injections of an engine take place. In a second hierarchy, the program instructions may be executed to generate control commands during the defined time periods. In a third hierarchy, the program instructions may be executed to adapt the control commands to a specified injector type. Finally, in a fourth hierarchy, the program instructions may be executed to map the adapted control commands to physical hardware configured to perform the series of fuel injections. Execution of the program instructions may be carried out in any desired combination of software executed by one or more processing elements, implemented in an FPGA, and/or coded in hardware.
