This paper introduces a new data-driven MPC structure based on two offline and online parts to achieve the robust constrained performance in an optimal scheme. In first step, according model matching condition, controller is designed reach tracking performance. addition, reduce effects of external disturbance, data-driven-based disturbance observer presented estimate disturbance. Therefore, rob...

This paper presents the robust design for chaotic cryptosystems. The cryptosystem combines cryptograph with chaotic synchronization. The hyperchaotic signals are synchronized between the encrypter and the decrypter based on observer gains. The technique of linear matrix inequality (LMI) is applied to determine the observer gains. A theorem has been proposed to guarantee the robust stabilization...

In disturbance-observer-based control, the closed loop system consists of a main feedback control loop and an inner disturbance observer loop. This paper presents a design method for a disturbance observer to satisfy closed loop performance specifications, provided that the main feedback controller is known. Taking advantage of certain fixedstructure disturbance observers, the disturbance obser...

In this paper we describe a control methodology for the navigation of an autonomous lighter-than-air vehicle based on visual input. The control system consists in a Linear Quadratic Regulator (LQR) and a Linear Quadratic Gaussian observer (LQG). Due to non-linearities in the actuators and in the radio frequency control system, some non-linear control terms are added. The additional terms lead t...

First, a suitable transformatio...

Many day-to-day activities require the dexterous manipulation of a redundant humanoid arm in complex 3D environments. However, position regulation of such robot arm systems becomes very difficult in presence of non-linear uncertainties in the system. Also, perturbations exist due to various unwanted interactions with obstacles for clumsy environments in which obstacle avoidance is not possible,...

In this paper, the voltage and frequency regulation of microgrid with unknown disturbances non-linear dynamics was studied. The disturbance observer designed sliding mode control (SMC) method used to realize secondary frequency. First, a distributed protocol reduce communication burden between generators solve deviations. Second, consensus for designed, based on idea multi-agent consensus, indi...

Leprosy is caused by Mycobacterium leprae infection and remains a major public health problem in many areas of the world. Challenges to its timely diagnosis result in delay in treatment, which is usually associated with severe disability. Although phenolic glycolipid (PGL)-I has been reported as auxiliary diagnostic tool, currently there is no serological assay routinely used in leprosy diagnos...
