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

This claim can be formally proved with mathematical induction. Persistent cookies are stored on your hard disk and have a pre-defined expiry date. From Wikipedia, the free encyclopedia. Subscribe to our newsletter Some error text Name. Here, a stabilized multiple-integrator system is built up from subsystems of already-stabilized multiple-integrator subsystems. In control theorybackstepping is a technique developed circa by Petar V.

Nonlinear Systems 3rd ed. These systems are built from subsystems that radiate out from an irreducible subsystem that can be stabilized using some other method. Views Read Edit View history. The backstepping approach provides a recursive method for stabilizing the origin of a system in strict-feedback form.

Sometimes, we also use a cookie to keep track of your trolley contents. 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.

In the two-integrator case, the upper single-integrator subsystem was stabilized yielding a new single-integrator system that can be similarly stabilized. 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. So it is critical to develop a single-step procedure; that procedure can be recursively applied to cover the many-step case. Fortunately, due to the requirements on the functions in the strict-feedback form, each single-step system can be rendered by feedback to a single-integrator system, and that single-integrator system can be stabilized using methods discussed above.

Because this strict-feedback system has a feedback-stabilizing control and a corresponding Lyapunov function, it can be cascaded as part of a larger strict-feedback system, and this procedure can be repeated to find the surrounding feedback-stabilizing control.

Backstepping Likewise, they are stabilized by stabilizing the smallest cascaded system and then backstepping to the next cascaded system and repeating the procedure. This recursive procedure can be extended to handle any finite number bacsktepping integrators. Cookies come in two flavours — persistent and transient. Hence, any strict-feedback system can be feedback stabilized using a straightforward procedure that can even be automated e.
