A general framework is introduced for iterative/adaptive controller design schemes by model unfalsification. An important feature of the schemes is their convergence near to the best possible controller given a set of model and controller structures. The problem of stability assured controller tuning is examined through unfalsified Riemannian bands of the Nyquist plot. Instability tolerant H ∞ and l 1 ‐norm‐based controller tuning schemes are introduced. Computational problems are discussed and a simulation is used to illustrate the new scheme.
