Isomorphic state observers and system signal robust filtering

The simple formalized procedure for synthesis of new type observers – isomorphic observers – is proposed. Was demonstrated that for the observed object the synthesis task decomposition allowing to generate separately and independently an isomorphic observer and filter exists.  The robust observer synthesis method is proposed that provides in conjunction with filters high quality of reproduction and filtering of linear system input signals in conditions of significant noise and parametrical disturbances. Examples of isomorphic observers and filters synthesis are given.
