Dual time–frequency domain system identification

Frequency Domain System Identification

Frequency domain versus time domain methods in system identification

For some reason I now forget, Keith Glover and I were asked to prepare a discussion paper on frequency and time domain methods in system identi cation by the organizers of the IFAC symposium on System Identi cation in Darmstadt 1979. I visited Keith in Cambridge in April 1979 to prepare our paper. It later evolved into an Automatica arcticle. Since then, there has been a useful development of s...

Using Domain Knowledge in Evolutionary System Identification

Two example of Evolutionary System Identi cation are presented to highlight the importance of incorportaing Domain Knowledge: the discovery of an analytical indentation law in Structural Mechanics using constrained Genetic Programming, and the identi cation of the repartition of underground velocities in Seimsi Prospection. Critical issues for sucessful ESI are discussed in the light of these r...

Evolutionary System Identification in the Time-Domain

This paper develops a genetic algorithm based multivariable system identification technique from plant step response data directly. Using this technique, globally optimised models for linear and nonlinear systems can be identified without the need of a differentiable cost function or linearly separable parameters. Results are validated against a benchmark identification problem and a laboratory...

Evolutionary system identification in the time domain

This paper develops a genetic algorithm based technique that may be used to identify multivariable system identification directly from plant step response data. Using this technique, globally optimized models for linear and non-linear systems can be identified without the need for a differentiable cost function or linearly separable parameters. Results are validated against a benchmark identifi...
