A new modified Smith predictor structure is presented with its associated tuning rules.

In this paper, we present a geometric method for describing the effects of the delay induced uncertainty on the stability of a standard Smith Predictor control scheme. The method consists of deriving the stability crossing curves in the parameter space defined by the nominal delay, and delay uncertainty, respectively. More precisely, we start by computing the crossing set, which consists of all...

is small. For large delays, the Smith predictor is applied to solve the instability problem and the scheme is proved to be robust against a small difference between the assumed delay and the actual delay. The analysis shows that bustness against delays in the boundary measurement.

Abtract: Time-delays (dead times) are found in many processes in industry. Time-delays are mainly caused by the time required to transport mass, energy or information, but they can also be caused by processing time or accumulation. The contribution is focused on a design of algorithms for adaptive digital control for processes with time-delay. The algorithm is based on pole assignment approach....

in this paper, behavior of teleoperation systems with modeling error and delay time error in smith predictor is discussed. in teleoperation systems, modeling error is inevitable. this paper discusses stability of teleoperation systems with modeling error. first, error of delay time in teleoperation systems by using of internet as communication channel is considered and the performance of smith ...

A mixed sensitivity problem is solved for dead-time systems. It is shown that for a given bound on the -norm causal stabilizing controllers exist that achieve this bound if and only if a related finite-dimensional Riccati equation has a solution with a certain nonsingularity property. In the case of zero time delay, the Riccati equation is a standard Riccati equation and the nonsingularity cond...

The Smith predictor is applied to the boundary control of damped wave equations with large delays at the boundary measurement. The instability problem due to large delays is solved and the scheme is proved to be robust against a small difference between the assumed delay and the actual delay. Copyright c ©2005 IFAC
