Using Tracking Differentiators in Designing Nonlinear Disturbance Observers for Uncertain SystemsNaser Kazemzadeh, Saeed BarghandanAbstractIn the present paper, a practical designing method has been proposed for a novel class of NDOs based on TD. Such NDOs can nearly estimate all uncertain disturbances (specifically disturbances without prediction information). Regarding the outstanding perform...

In this paper‎, ‎a synthesis method based on robust model predictive control is developed for compensation of uncertain time-delays in networked control systems with bounded disturbance‎. ‎The proposed method uses linear matrix inequalities and uncertainty polytope to model uncertain time-delays and system disturbances‎. ‎The continuous system with time-delay is discretized using uncertainty po...

Professor drivers, including racing can drive cars to achieve drift motions by taking control of the steering angle in high tire slip ratios, which provides a way improve driving safety autonomous vehicles. The existing studies be divided into two kinds based on analysis methods, and theory-based is chosen this study. Because recent theory most applied for planar models with neglect rollover ac...

This paper is concerned with the consensus tracking problem of high order MIMO nonlinear multi-agent systems. The agents must follow a leader node in presence of unknown dynamics and uncertain external disturbances. The communication network topology of agents is assumed to be a fixed undirected graph. A distributed adaptive control method is proposed to solve the consensus problem utilizing re...

This paper addresses the chaos control of uncertain chaotic nonlinear gyros with unknown parameters. In general, the underlying class of gyros may be perturbed by external disturbances with different sources. Depending on the characteristics of uncertain parameters and disturbances, two different adaptive-based control algorithms are proposed. In the first method, an adaptive H∞ controller is d...

Fiber optical gyroscopes (FOGs) have been applied widely in navigation for mobile robots. The precision of outputs from FOGs is affected significantly by uncertain disturbances due to road conditions in practice. It is urgent to eliminate uncertain disturbances from outputs of sensors in harsh environments. This paper proposes an adaptive method of signal processing base on wavelet and fuzzy lo...

Precise control is critical for robots, but it difficult to obtain an accurate dynamic model of the robot due presence modeling errors and uncertainties in complex working environment, resulting decreased performances. The article proposes a method designing digital controller output tracking disturbed repetitive manipulators that does not require mathematical controlled with goal improving acc...
