Robustness of the controller becomes major important factor in active engine mounting system to ensure the vibration of the engine can be attenuated in entire range of operating speed. As robustness is the main advantage of sliding mode control, it has been proposed for vibration control applications. However, most of the proposed sliding mode control are using linear sliding surface. In addition,...
This paper introduces improvement in a practical nominal characteristic trajectory following (NCTF) controller for two mass point-to-point (PTP) rotary positioning systems. The NCTF controller consists of a nominal characteristic trajectory (NCT) as a movement reference and a compensator. The objective of the NCTF controller is to make the object motion follow the NCT and end at its origin. The NCTF...
In this paper, a nominal characteristic trajectory following (NCTF) controller for point-to-point (PTP) positioning system for two mass rotary system is introduced and its performance is evaluated. Generally, the NCTF controller consists of a nominal characteristic trajectory (NCT) and a compensator. The objective of the NCTF controller is to make the object motion follow the NCT and end at its origin...

In this paper, the state feedback control design problem for tracking control of a flexible link manipulator is considered. The calculation of state feedback control gains is conventionally handled by pole placement method or LQR method via Riccati equation. Unfortunately, they still possess trial and error approach of choosing some parameters. Particularly, choosing elements of Q and R matrices in...
The needs of powerful engine and lighter car body has adverse effect to the vibration occurred in the car. Obviously the presence of the engine vibration will imposed to the discomfort of the driver and passengers as well. To isolate the vibration, active engine mounting (AEM) has been proposed as the new generation of engine mounting. The control method becomes key factor of successfulness of AEM...
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...
