Self-tuning control of bilinear systems. (English) Zbl 0623.93043
The authors present a self-tuning pole-placement for a class of single- input single-output bilinear systems. In order to implement a suboptimal pole-placement control strategy, they propose a time-step quasi- linearization procedure within ane extended state-space framework, recursively updated.
A two-tier algorithm, involving the use of both variable forgetting factor reset and covariance reset is proposed. The reset procedure is repeatedly initiated, whenever a fault condition, indicative of large modelling errors, is identified. This leads to an increased alertness and adaptivity of the algorithm.
Simulation studies suggest an improved performance, in terms of both system stability and parameter tracking ability.
