Abstract

In the paper is described development of predictive controller of combustion engine. The basic part of control system is predictive model describing future engine behavior in transient conditions. Accurate identification of controlled system, combustion engine in our case, is very important for high level of control precision. Typical engine operation is defined by driving cycle, which is used for engine operation parameters identification. Developed predictive control system was subsequently tested using software‐in‐the‐loop technique.

V tomto článku je popsán vývoj prediktivního řídicího systému pro spalovací motor. Základem prediktivního kontrolního systému je prediktivní model popisující chování v krátké budoucnosti přechodového děje. Přesná identifikace řízené soustavy, v našem případě spalovacího motoru, je velmi důležitá z hlediska přesnosti řízení. Typický provoz motoru je definován jízdním cyklem, který byl z tohoto důvodu použit pro identifikaci stavových parametrů motoru. Vyvinutý prediktivní systém řízení byl následně otestován s využitím software‐in‐the‐loop techniky.
