This article studies model reference adaptive control (MRAC) for a class of stochastic discrete time systems with delays in the input. In particular, unified fully probabilistic framework is established to develop solution MRAC, where controller minimizer Kullback-Leibler divergence between actual and desired joint probability density functions tracking error controller. The developed quite gen...

Model reference adaptive control (MRAC) offers the potential to adapt in real-time changes performance of small unmanned air vehicles. There are significant challenges with their use, however, primarily implementation and assurance long-term system stability. This paper presents flight test results for a combined model (CMRAC) law applied height loop multirotor. Key features include CMRAC basel...

This paper presents the implementation of an adaptive control approach to ball and beam system (BBS). The dynamics a BBS are non-linear, in implementation, uncertainty system's parameters may occur. In this research, linear state-feedback model reference (MRAC) is used synchronize states with given model. research investigates performance MRAC method for that applied non-linear or BBS. order ge...

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...

This paper presents a new intelligent agent supervisory loop based approach for dynamic system control. The scheme consists of three software agents that work in an autonomous manner for the precision control of a system that shows multiple modes and drastic parametric ‘jumps’. The first two agents are based on artificial intelligent techniques (fuzzy systems and Radial Basis Function Neural Ne...

By using the concept of on-line goal adaptation, we develop a new paradigm of performance shaping in MRAC. The general idea is to replace the single reference model generated trajectory in classical adaptive designwith a tube referencemodel. Two alternative adaptive control schemes that lead to tractable design formulations are developed in which the performance is adapted on-line to satisfy a ...

Two model-based fault-tolerant control design strategies are presented for a Diesel Engine Generator (DEG) working as a master generation unit in an islanded microgrid consisting of a hybrid wind-diesel-photovoltaic power system with a Battery Storage System (BSS). A Model Predictive Control (MPC) scheme and a Model Reference Adaptive Control (MRAC) scheme have been selected for precise and sta...
