As an alternative of the Lyapunov function-based design of adaptive controllers the Fixed Point Transformation based Adaptive controller was introduced that in the first step transforms the control task into a Fixed Point Problem then so solves it via iteration that during one digital control step one step of iteration happens. In the actual step this scheme takes into consideration the controlled system's response obtained for the control action in the previous step, therefore it applies delayed feedback that makes it very flexible in the adaptive control of time-delayed systems. In transforming the control problem into a fixed point problem countless mathematical possibilities exist. Till now only a few versions were in use. On the basis of certain old antecedents in this paper a novel version is suggested that creates abstract rotations in the n dimensional space on the basis of the generalization of the Rodrigues formula. Its main advantage is its simplicity, easy geometric interpretation, lucidity, and better fitting to the features of the particular control task. Its applicability is exemplified by simulations for the adaptive control of two mass-points coupled by nonlinear springs.

We call an electronic robust one then, if it the stress-like electronic change without a breakdown, possibly beside a minimal damage, not disturbing the normal function possibly, tolerates it. Not really definable the extreme changes quantity and his qualitative parameter, and the measure of the robustness. It was thawing out in robust electronics applications electronic circuit redundancy, the safe, in this manner advantageously can be used the programmable analogous electronic circuits (field programmable analog array, FPAA). Using of these FPAA circuits can be developed such robust architectures which are redundant, adaptive and reconfigurable. Additional benefit, it is you that the analogous system may be attached to an embedded controller or a computer through a digital surface to, that the adequately chosen feedbacks intervene in the function of the electronic circuit.

The field programmable analog array (FPAA) are advantageously useful different functional units, electronic circuits, part of electronic circuit, onto his forming. In this direction there is an opportunity if the cooperation of embedded informatics device and FPAA is possible especially. Perspective that solution, where the electronic circuit to be worked up some-, or more adaptivity plays himself with a partial self-organization in that manner the topology, regarding the parameters of the single elements.

In civil and industrial areas often a task to log the data of an embedded system. In some applications the redundant data storage and archiving is required. In the field it can be occur, that the device suffers some electromagnetic impact. It can cause for example, some high current industrial device, a near lightning strike, a transient electromagnetic disturbance, EMP jamming, etc. It can cause damage in the data measured by the embedded system. In this paper shows an architectural solution to keep the data safe, or flag the exact part of the data, which can contain errors.

Well knowing solution in the electronic circuit theory at present days, the fine setting of the parametrical values of the whole-, and part of the circuit, by the change of one or more parameter of electronic parts. We get more advantage, when not only the parametrical values, but the circuit topology is changeable too. The actuality of this approach is daily by the using of the field programmable analogue arrays in the analogue circuits in the reconfigurable robust systems by the cooperation of the embedded informatics devices or microcontroller.
