Unlike standard Model Reference Adaptive Control (MRAC), Optimal Control Modification (OCM) has been shown to be a promising MRAC modification with robustness and analytical properties not present in other adaptive control methods. This paper presents an analysis of the OCM method, and how the asymptotic property of OCM is useful for analyzing and tuning the controller. We begin with a Lyapunov...

Exact decentralized output-feedback Lyapunov-based designs of direct model reference adaptive control (MRAC) for linear interconnected delay systems with MIMO subsystems are introduced. The design process uses a co-ordinated decentralized structure of adaptive control with reference model co-ordination which requires an exchange of signals between the different reference models. It is shown tha...

In this paper a combination of Fuzzy Logic Control (FLC) and Model 1 Reference Adaptive Control (MRAC) will be developed to stabilize and control a 2 fixed-wing unmanned aerial vehicle (UAV). The control must be able to direct the 3 airplane towards different waypoints while at the same time maintaining the UAV 4 stable. Also, the control should be transferable to similar UAV models with little...

This paper presents a unit vector based output-feedback model-reference adaptive control (UV-MRAC) for uncertain multi-input-multi-output (MIMO) linear systems. Some features of this new algorithm are: (i) Less restrictive a priori knowledge about the high frequency gain matrix of the plant is required. (ii) It applies to plants of any uniform relative degree. (iii) The closed loop system is ex...

The chapter presents an approach to control the biped humanoid robot to ambulate through human imitation. For this purpose a human body motion capturing system is developed using tri-axis accelerometers (attached to human legs and torso). The tilt angle patterns information from the human is transformed to control and teach various ambulatory skills for humanoid robot bipedalism. Lyapunov stabi...

Magnetic Levitation is a process in which an object suspended with the support of magnetic field. Despite being unstable system, Systems (MAGLEV) have profound applications various fields engineering. MAGLEV systems are sensitive, unstable, and nonlinear uncertainties always pose challenge Controller Design. As solution, adaptive controllers came into existence adaptation mechanisms to cover sy...
