In this paper a modified Smith predictor for linear delayed haptic interaction is presented. The objective is to design a feedback law which compensates the time delay by its somehow elimination from the characteristic equation of the closed loop system. This method is robust within a certain safe prediction interval. The applicability of Smith predictor in the case of haptic interaction using ...

An approach to control integrating processes with elevated deadtime using a Smith predictor sliding mode controller is presented. A PID sliding surface and an integrating first-order plus deadtime model have been used to synthesize the controller. Since the performance of existing controllers with a Smith predictor decrease in the presence of modeling errors, this paper presents a simple approa...

Filtered Smith predictors are well established for controlling linear plants with constant time delays. Apart from this classical application scenario, they also employed within networked control loops, where the measurements sent in separate packets over transmission channels that subject to time-varying Consequently, tools stability analysis, e.g., delay systems, have be extended facilitate a...

This contribution presents a solution to the dead time problem that is known as "Smith Predictor." allows us use already techniques for design of controllers systems without delay and adapt them with delay. "As goal, it aims achieve response system delay, has same dynamic characteristics example, step input, but displaced in value

Many industrially important processes feature both nonlinear system dynamics and a process deadtime. Powerful deadtime compensation methods, such as the Smith predictor, are available for linear systems represented by transfer functions. A Smith predictor structure in state space for linear systems is presented first and then directly extended to nonlinear systems. When combined with input /out...

In this paper, a new approach is presented based on relay autotuning of a plant to find parameters for its control using a Smith predictor. A Smith predictor configuration is represented as its equivalent internal model controller (IMC) which provides the parameters of the proportional-integral (PI) or proportional-integral-derivative (PID) controller to be defined in terms of the desired close...
