So the final feedback-stabilizing control law is. Cookies come in cimmande flavours – persistent and transient. Subscribe to our newsletter Some error text Name. For example, at loot. Before discussing the recursive procedure for the general multiple-integrator case, it is instructive to study the recursion present in the two-integrator case.

Views Read Edit View history. With a small modification, the integrator backstepping approach can be extended to handle all strict-feedback form systems. Hence, this process is known as backstepping.

At iteration ithe equivalent system is.

Backstepping – Wikipedia

Control theory Nonlinear control. Please click the link in that email to activate your subscription. Let’s connect Contact Details Facebook Twitter. Nonlinear Systems 3rd ed.


In control theorybackstepping is a technique developed circa by Petar V. As in many-integrator backstepping, the single-step procedure can be completed iteratively to stabilize an entire strict-feedback system.


Consider the simple strict-feedback system. The process terminates when the final external control is reached.

That is, consider the dynamical system. Kokotovic and others [1] [2] for designing stabilizing controls for a special class of nonlinear dynamical systems. By using this site, you agree to the Terms of Use and Privacy Policy.

This claim can be formally proved with mathematical induction. In both cases you should know how to switch cookies back on! Hence, the process “steps backward” nackstepping x out of the strict-feedback form backstepoing until the ultimate commaned u is designed.

Hence, any strict-feedback system can be feedback stabilized using a straightforward procedure that can even be automated e. Retrieved from ” https: Hence, any system in this special many-integrator strict-feedback form can be feedback stabilized using a straightforward procedure that can even be automated e.

These systems connect a series of integrators to the input of a system with a known feedback-stabilizing control law, and so the stabilizing approach is known as integrator backstepping. Please refer to our privacy policy for more information on privacy at Loot.

This process is known as backstepping because it starts with the requirements on some internal subsystem for stability and progressively steps back out of the system, maintaining stability at each step.

These systems are built from subsystems that radiate out from an irreducible subsystem that can be stabilized using some other method. Here, a stabilized multiple-integrator system is built up from subsystems of already-stabilized multiple-integrator subsystems.

Sometimes, we also use a cookie to keep track of your trolley contents. This recursive procedure can be extended to handle any finite number of integrators. Likewise, they are stabilized by stabilizing the smallest cascaded system and then backstepping to the next cascaded system and repeating the procedure. This page was last edited on 12 Augustat Transient cookies are kept in RAM and are commmande either when you close all your browser windows, or when you baclstepping your computer.

This system is a cascade connection of an integrator with the x subsystem i.

Upper Saddle River, NJ: Authentication ends after about 15 minutues of inactivity, or when you explicitly choose to end it. Before describing the backstepping procedure for general strict-feedback form dynamical systemsit is convenient to discuss the approach for a smaller class of strict-feedback form systems. Because of this recursive structure, the designer can start backdtepping design process at the known-stable system and “back out” new controllers that progressively stabilize each outer subsystem.
