Abstract—In this paper, the analytical tuning rules of IMC-PID controller are presented for the multivariable Smith predictor that involved the ideal decoupling. Accordingly, the decoupler is first introduced into the multivariable Smith predictor control system by a well-known approach of ideal decoupling, which is compactly extended for general nxn multivariable processes and the multivariabl...

The problem discussed in this paper is the effect of latency time on the OGY chaos control methodology in multi chaotic systems. The Smith predictor, rhythmic and memory strategies are embedded in the OGY chaos control method to encounter loop latency. A comparison study is provided and the advantages of the Smith predictor approach are clearly evident from the closed loop responses. The comple...

This paper proposes an adaptive wireless-network-induced delay compensation technique for Wireless Sensor and Actuator Network (WSAN). It is well known that network delays and packet losses over wireless network incur a great challenge over performance as well as stability of WSAN-based control systems. This paper presents a time-varying delay compensator exploiting Adaptive Smith Predictor wit...

This paper presents a review of the main dead-time compensators (DTC) described in literature. The paper analyses the basic Smith predictor (SP) showing its advantages and drawbacks. DTC structures designed to improve closed-loop characteristics and to control unstable systems are described. The paper concludes with some recommendations for designing dead-time compensator controllers. r 2007 El...

This paper presents a control methodology that provides transparency and stability robustness in bilateral telemanipulation systems that include a significant time delay in the communication channels. The method utilizes an adaptive Smith predictor to compensate for the time delay, and incorporates a previously published loop shaping approach to design a compensator for transparency and stabili...

In this paper, a model-predictive trajectory-tracking control applied to a mobile robot is presented. Linearized tracking-error dynamics is used to predict future system behavior and a control law is derived from a quadratic cost function penalizing the system tracking error and the control effort. Experimental results on a real mobile robot are presented and a comparison of the control obtaine...

The paper extends recent work on a modi"ed Smith predictor strategy, which leads to signi"cant improvements in its regulatory capacities for reference inputs and disturbances. High-order or long dead time stable, integrating and unstable plants are modelled as lower-order plant models with a longer time delay. The controllers are designed so that the delay-free component of the output is tuned ...

Five control systems loosely corresponding to primate saccadic, vergence, pursuit, vestibule-ocular, and head control operate on a simulated two-eyed robot head maneuvered by a robot arm. The goal is to get some qualitative understanding of the interaction of such reflexes under various assumptions. The simulation is meant to be relevant to U. Rochester's robot. Thus it incorporates kinematics ...

A practical active disturbance rejection control (ADRC) solution is proposed for the furnace temperature system. Employing a linear reduced-order model with optimized parameters, the practical ADRC is simple to use, easy to tune and energy-efficient in dealing with the uncertainties and disturbances in plant dynamics. Through the order reduction in both the plant model and the state observer, w...

This paper presents a non-linear control scheme to deal with dead-time processes, specially for systems where fast closed-loop responses are required. The control scheme is based on the combination of two control strategies appeared in the literature to deal with dead-time processes, the Filtered Smith Predictor (FSP), which is a Smith Predictor (SP) including a filter to improve the robustness...
