Flatness-based automotive solenoid valve control
IFAC Proceedings Volumes, 2004 Abstract This paper considers the control of solenoid valve actuators used for gas exchange in internal combustion engines. Solenoid valves offer performance benefits over traditional camshaft-based valve timing. Maintaining the impact velocity of the armature and valve is an important performance specification. Flatness-based control provides linear

Flatness-based adaptive control (FBAC) for STATCOM [PDF]
Electric Power Systems Research, 2015 Abstract This article proposes a new method, called the flatness-based adaptive control (FBAC), for STATCOM voltage regulation. By this method, the nonlinear STATCOM variables can be easily and exactly controlled by controlling flat output without solving differential equations.

Flatness-based control of a two-degree-of-freedom platform with pneumatic artificial muscles [PDF]
Journal of Dynamic Systems Measurement, and Control, 2017 Pneumatic artificial muscles (PAMs) are an interesting type of actuators as they provide high power-to-weight and power-to-volume ratio. However, their efficient use requires very accurate control methods taking into account their complex and nonlinear ...
