A Measure of Coefficient Quantization Errors for Linear Discrete-Time State-Space Systems

摘要

This paper proposes a measure of coefficient quantization errors for linear discrete-time state-space systems. The proposed measure of state-space systems agrees with the actual output error variance since it is derived from the exact evaluation of the output error variance due to coefficient devia- tion. The measure in this paper is represented by the control- lability and the observability gramians and the state covariance matrix of the system.
