Analysis of a Probing Control Strategy
(2002) In Technical Reports TFRT-7602- Abstract
- In this paper we analyse an extremum controller based on a pulse technique. The idea is to superimpose probing pulses to the control signal and use the size of the pulse response in the output for feedback. The probing control strategy has been used with success for the control of the substrate feeding in E. coli cultivations. The stability analysis is done here for systems of Hammerstein type with a piecewise affine nonlinearity. Stability regions of the closed-loop system are derived by solving suitable linear matrix inequalities. Some robustness results with respect to uncertainty in the plant are also given.
