This paper studies behavior of non-ideal vibratory micromachined gyroscopes. The use of methods of motion decomposition  is the essence of the proposed analytical approach. The method is based on partitioning the equations of motion on fractions which are changing in different time scales. The approach allows rapid simulation of the long-term response of the gyroscope in presence of imperfections. The central result of the paper is the classification of errors in accordance with their in uence on the gyroscope behavior.
