Abstract
: This paper gives an overview of di#erent techniques for solving the dual control problem. The optimal solution can quite straightforwardly be characterized. The solution is, however, numerically demanding. A large number of suboptimal dual controllers have been developed over the years and the paper gives an overview and discussion of di#erent approaches. Keywords: Adaptive control, Optimal adaptive control, dual control, self-tuning control. 1. INTRODUCTION Feldbaum's seminal work, Feldbaum #1960# and Feldbaum #1961#, gave the foundation for the dual control problem. The main idea is that in controlling an unknown system it is necessary to let the controller have dual goals. First, the controller must control the process as well as possible. Second, the controller must inject a probing signal to get more information about the unknown system. By gaining more information better control can be achieved in future steps. The main problem is that to get a better model it is necessa...
