Dead-time compensators: A survey
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...
متن کاملThe Delay Margin of Dead-time Compensators
Dead-time compensators (DTCs) are frequently regarded as being excessively sensitive to uncertainty in the loop delay. This claim, however, is based mostly on empirical studies rather than on any rigorous analysis. In particular, despite existing literature on the calculation of the delay margin, μd, there appears to be no study of the underlying reasons of such a sensitivity. In this paper we ...
متن کاملDead-time compensators: performance and robustness issues
This paper will compare a number of PID and predictive controller strategies to compensate processes modelled in first order lag plus time delay (FOLPD) form. The performance and robustness of the resulting compensated systems are evaluated analytically (where appropriate) and in simulation.
متن کاملA numerical approach for variable-order fractional unified chaotic systems with time-delay
This paper proposes a new computational scheme for approximating variable-order fractional integral operators by means of finite element scheme. This strategy is extended to approximate the solution of a class of variable-order fractional nonlinear systems with time-delay. Numerical simulations are analyzed in the perspective of the mean absolute error and experimental convergence order. To ill...
متن کاملA Unified IMC based PI/PID Controller Tuning Approach for Time Delay Processes
This paper proposes a new PI/PID controller tuning method within filtered Smith predictor (FSP) configuration in order to deal with various types of time delay processes including stable, unstable and integrating delay dominant and slow dynamic processes. The proposed PI/PID controller is designed based on the IMC principle and is tuned using a new constraint and without requiring any approxima...
