Sliding Mode Control and Observation

By Yuri Shtessel, Christopher Edwards, Leonid Fridman, Arie Levant

The sliding mode regulate method has confirmed potent in facing advanced dynamical platforms stricken by disturbances, uncertainties and unmodeled dynamics. powerful keep an eye on know-how in response to this system has been utilized to many real-world difficulties, specifically within the components of aerospace regulate, electrical strength structures, electromechanical structures, and robotics. Sliding Mode keep watch over and Observation represents the 1st textbook that starts off with classical sliding mode regulate ideas and progresses towards newly constructed higher-order sliding mode keep watch over and commentary algorithms and their applications.

The current quantity addresses a number sliding mode regulate concerns, including:

*Conventional sliding mode controller and observer design

*Second-order sliding mode controllers and differentiators

*Frequency area research of traditional and second-order sliding mode controllers

*Higher-order sliding mode controllers and differentiators

*Higher-order sliding mode observers

*Sliding mode disturbance observer dependent keep an eye on

*Numerous purposes, together with reusable release car and satellite tv for pc formation keep watch over, blood glucose rules, and motor vehicle steerage keep watch over are used as case studies

Sliding Mode keep an eye on and Observation is geared toward graduate scholars with a easy wisdom of classical keep watch over concept and a few wisdom of state-space equipment and nonlinear structures, whereas being of curiosity to a much broader viewers of graduate scholars in electrical/mechanical/aerospace engineering and utilized arithmetic, in addition to researchers in electric, desktop, chemical, civil, mechanical, aeronautical, and commercial engineering, utilized mathematicians, regulate engineers, and physicists. Sliding Mode keep watch over and Observation presents the required instruments for graduate scholars, researchers and engineers to robustly regulate complicated and unsure nonlinear dynamical structures. workouts supplied on the finish of every bankruptcy make this an awesome textual content for a complicated course taught up to the mark theory.
