Fujimoto and Kawamura : Robust Servo - System Based on Two - Degree - of - Freedom Control with Sliding Mode
نویسنده
چکیده
|A robust servo-system, based on a combination of linear robust control and sliding mode control have been proposed. This new control system can be said to be a non-linear system (sliding mode control system) which has a inner loop of linear control (two-degree-of-freedom control). Due to this inner loop of linear control, a disturbance is strongly suppressed but not completely. Then, the outer loop of sliding mode control eliminates this disturbance suppression error. First in this paper, a linear robust-servo design of twodegree-of-freedom control system is shown. Next, a sliding mode control is applied to this system and the disturbance suppression characteristics are discussed. Then, through the simulations and experiments, it is proved that the introduction of non-linear control (sliding mode) drastically improves the disturbance suppression characteristics of a linear system (two-degree-of-freedom control).

متن کاملGalloping and VIV control of square-section cylinder utilizing direct opposing smart control force
An adaptive fuzzy sliding mode controller (AFSMC) is adopted to reduce the 2D flow-induced vibration of an elastically supported square-section cylinder, free to oscillate in stream-wise andtransverse directions in both lock-in and galloping regions. The AFSMC strategy consists of a fuzzy logic inference system intended to follow a sliding-mode controller (SMC), and a robust control syste...
متن کاملA Novel Robust Adaptive Trajectory Tracking in Robot Manipulators
In this paper, a novel adaptive sliding mode control for rigid robot manipulators is proposed. In the proposed system, since there may exist explicit unknown parameters and perturbations, a Lyapunov based approach is presented to increase system robustness, even in presence of arbitrarily large (but not infinite) discontinuous perturbations. To control and track the robot, a continuous controll...
