Original abstract

An electronic throttle consists of a DC motor, spur gears, a return spring, a position sensor, power electronics and an electronic control unit. Fast and precise position control of this electromechanical system is relatively difficult due to very high friction and the strong nonlinearity of the spring. Simple application of linear control, such as PID, fails. In this paper, two new controller structures suitable for different reference signal types are described. The key component of the position controller is the friction compensator based on either/both feedforward or feedback principles. The quality of the resulting behavior was measured using several criteria including the measure of control activity around the equilibrium position. The control activity directly influences the vibration, the noise and the wear of the servo system. The proposed controllers demonstrated superior behavior compared with other published structures.

Czech abstract

Elektronická škrticí klapka se skládá z DC motoru, převodovky, vratné pružiny, polohového sensoru, výkonové elektroniky a řídicí jednotky. Rychlé a přesné polohové řízení tohoto elektromechanického systému je relativně obtížné z důvodů vysokého tření a silné nelinearity pružiny. Jednoduché algoritmy jako je PID selhávají. V tomto článku jsou navrženy dvě nové struktury řídicího členu vhodné pro různé typy referenčního signálu. Klíčovou komponentou regulátoru je kompensátor tření založený na zpětnovazebním nebo dopředném principu. Kvalita výsledného chování byla posouzena multikriteriálním hodnocením.
