A good book to learn adaptive control Hi guys I've been reading the posts here for a while and I came across the post about L1 adaptive control and this got me interested in adaptive control. I have very basic experience in PI controllers.

Discrete-Time Neural Observers. This chapter presents the design of an adaptive recurrent neural observer for nonlinear systems, whose mathematical model is assumed to be unknown. The observer is based on a recurrent high order neural network (RHONN), which estimates the state vector of the unknown plant dynamics and it has a Luenberger structure.

Abstract: This paper proposes a sensorless vector control that combines two discrete-time observers to estimate the rotor speed and position of permanent magnet synchronous machines (PMSM). The first one is a sliding mode (DSM) current observer and the second one is an adaptive electromotive force (EMF) observer.

Initially, the sliding conditions that assure the sliding motion Cited by: This graduate-level text focuses on the stability of adaptive systems, and offers a thorough understanding of the global stability properties essential to designing adaptive systems.

Its self-contained, unified presentation of well-known results establishes the close connections between seemingly independent developments in the field.

A systematic and unified presentation of the fundamentals of adaptive control theory in both continuous time and discrete time Today, adaptive control theory has grown to be a rigorous and mature discipline.

As the advantages of adaptive systems for developing advanced applications grow apparent, adaptive control is becoming more popular in many fields of engineering and science.

Using linear models, a dynamic observer is designed to detect malfunctions. The book presents solutions for the output trajectory tracking problem of unknown nonlinear systems based on four schemes.

For the first one, a direct design method is considered: the well known backstepping method, under the assumption of complete state measurement; the second one considers an indirect method, solved with the block control and.

And observer gain matrix and adaptive adjusting rule of the fault estimator are designed. Furthermore, the adaptive regulating algorithm can guarantee the first-order difference of a Lyapunov discrete function to be negative, so that the observer is ensured to be stable and fault estimation errors are by: 4.

Discrete-Time Systems comprehend an important and broad research field.

Chapter 5 deals with various types of model reference adaptive control in continuous time, starting from the simplest scheme where only one parameters is adapted and progressing to more general SISO : Victor M. Becerra. This paper deals with the problem of fault diagnosis (FD) for a class of nonlinear systems in the presence of actuator failures.

The scheme is based on a discrete-time diagnostic observer which computes an estimate of the system's state. To cope with the uncertainties and discretization errors, a discrete-time adaptive law is developed, based on a parametric model of the uncertain terms.

Adaptive observers. Observer-based compensation in the frequency-domain. has been to remedy this omission by presenting a comprehensive and unified theory of observers for continuous-time and discrete -time linear systems.

The book is intended for post-graduate students and researchers specializing in control systems, now a core subject in. Continuous-discrete-time adaptive observers for nonlinear systems with sampled output measurements: Authors: This paper considers the continuous-discrete-time adaptive observer (CDAO) design for a class of nonlinear systems with unknown constant parameters and sampled output measurements.

The proposed observer is actually an impulsive. This paper proposes a new class of observers, called adaptive impulsive observer (AIO). AIO is capable to give continuous estimation for the states of a continuous nonlinear system by using the output of the system just at discrete impulse times.
