On The Approximate Decoupling Of Linear Stochastic Systems
Ali H. Bamani, G.K.F. Lee · 2005
In this paper, the decoupling problem for systems with additive noise is addressed. The decoupled model is initially constructed in the absence of noise. By imbedding feedforward and constant o utput feedback matrices into a control structure, a performance index can be formulated, representing an error between the output of a desired model and the output o f the actual system. Optimization of this performance measure results in the parametric design for the feedback and feedforward matrices which decouple the system in spite of external noise d isturbances.
