free chattering fuzzy sliding mode controllers to robotic tracking problem
sliding mode control (smc) is a powerful approach to solve the tracking problem for dynamical systems with uncertainties. however, the traditional smcs introduce actuator chattering phenomenon which performs a desirable behavior in many physical systems such as servo control and robotic systems, particularly, when the zero steady state error is required. many methods have been proposed to el...
متن کاملChattering attenuation in sliding mode control systems
In this paper sliding mode control systems arc considered and a new technique to attenuate chattering is proposed. The technique employs simple , first-order dynamical devices , i.e . an integrator or a low-pass filter, to compensate in part for unknown and changing dist urbance. As a result of this compensation, the magnitnde of the discontinuous control term is essentially reduced. The term d...
متن کاملChattering free full-order sliding-mode control
In conventional sliding-mode control systems, the sliding-mode motion is of reduced order. Two main problems hindering the application of the sliding-mode control are the singularity in terminal slidingmode control systems and the chattering in both the conventional linear sliding-mode and the terminal sliding-mode control systems. This paper proposes a chattering-free full-order terminal-slidi...
متن کاملChattering Elimination with Fuzzy Sliding Mode Control in Parallel Robots
Accuracy of tracking and robustness are very important specifications in control of parallel robots. Classical control methods could not satisfy these requirements in parallel robots, simultaneously. Sliding mode control solves problems of accurate tracking, but it is not robust enough because of influence of chattering phenomena. Implementation of fuzzy logic in sliding mode enhances robustnes...
متن کاملRobust Chattering Free Sliding Mode Control of Servo Drives
A new discrete-time control algorithm has been developed by combining Variable Structure Systems (VSS) and Lyapunov design. It possesses all the good properties of the sliding mode control and avoids the unnecessary discontinuity of the control input, thus eliminating chattering which has been considered as a serious obstacle for applications of VSS. A unified control approach for the stator cu...
