| Summary: | This paper discusses terminal sliding mode control
for active engine mounting (AEM) system to isolate vehicle
engine body vibration. The engine vibration may occur due to
road irregularities, at low frequency, and also reciprocating
mechanism of the piston in the engine, at high frequency about
20 – 40 Hz. Active engine mounting system is designed to deal
with isolation of vibration in high level frequency. A number of
controllers for AEM system have been proposed. One of them is
sliding mode control. However, there is no systematic method to
determine sliding surface for conventional sliding mode
technique to assure the system will be asymptotically stable.
The main advantage of the proposed controller compared to the
conventional (linear) sliding mode control is that the sliding
motion to the origin (stable condition) can be reached in finite
time by introducing the nonlinear sliding surface based on the
concept of terminal attractors. The result shows that terminal
sliding mode control not only able to attenuate the vibration but
also robust to the different type of disturbance and parametric
uncertainties such as mass, stiffness, and damping coefficient. |
