The checking and correction of the analog and hybrid computation by the redundant variables method

It is the purpose of the report to discuss the method of mistakes detection and that of partial selfrepair computing process. The method is based on the introduction of redundant variables and additional conditions, that are used as test conditions. The method allows to check and correct the whole computing process, and even to check and correct the work of the compiler of the program. It permits to reduce or fully eliminate mistakes, caused by systematic and random malfunctions, an operational amplifier zero drift, imperfection of computing algorithms, round off errors etc.
