Sliding Mode Control - ENCYCLOPEDIA OF LIFE SUPPORT.
In this paper, a fuzzy-sliding mode control scheme is proposed to manage the oscillation and chatter appearing in machining operation by adjusting the feed rate. The robotic machining dynamics is first analyzed to identify the parameters with focus on the system stiffness and the behavior during machining process. A controller consisting of a fuzzy estimation enginery which can determine the.

This paper presents a effective speed control of permanent magnet brushless DC motor drive using sliding mode controller based on reaching law. This drive system provides the advantages of PMBLDC motor and can be used in light electric vehicles and other adjustable speed drive applications. Speed regulation of a permanent magnet BLDC motor drive with various cases of reaching law based on.
A sliding mode observer, like sliding control, is usually a discontinuous observer. In this paper the second approach is applied and we extend the work of Koshkouei and Zinober (7) to multivariable systems. First some results relating to sliding dynamics are presented, and then an observer for a system which may not satisfy the matching condition, is developed. The main problems in sliding.
Abstract: Sliding-mode control (SMC) has been studied extensively for over 50 years and widely used in practical applications due to its simplicity and robustness against parameter variations and disturbances. Despite the extensive research activities carried out, the key technical problems associated with SMC remain as challenging research questions due to demands for new industrial.
Sliding Mode Control: The Delta-Sigma Modulation Approach, combines rigorous mathematical derivation of the unique features of Sliding Mode Control and Delta-Sigma modulation with numerous illustrative examples from diverse areas of engineering. In addition, engineering case studies demonstrate the applicability of the technique and the ease with which one can implement the exposed results.
Aiming at the problem of fixed-time trajectory tracking control for high-order dynamic systems with external time-varying disturbance and input dead-zone, an adaptive fixed-time sliding mode control algorithm is proposed by employing a fixed-time sliding mode disturbance observer (FTSMDO) and high-order fixed-time sliding mode algorithm. Firstly, a FTSMDO is presented for the problem that.
