Linear Feedback Decoupling - Transfer Function Analysis
نویسنده
چکیده
Abstruct-The problem of linear system decoupling is examined based on recent results on linear feedback. New insight is obtained, through which resolution of the decoupling problem is accomplished by calculations, performed directly on the given transfer matrix. Computation of the decoupling compensators follows by easy constructions. The problem of feedback block decoupling with internal stability is also formulated and resolved.

Solvability conditions for disturbance decoupling problems with static measurement feedback
Two well-known disturbance decoupling problems are considered. A checkable necessary and su cient condition is derived under which the disturbance decoupling problem with static measurement feedback (DDPKM) is solvable for a class of multi-input and multi-output linear time-invariant systems, which have a left invertible transfer matrix function from the control input to the controlled output....
متن کاملClosed-loop structure of decouplable linear multivariable systems
Considering a controllable, square, linear multivariable system, which is decouplable by static state feedback, we completely characterize in this paper the structure of the decoupled closed-loop system. The family of all attainable transfer function matrices for the decoupled closed-loop system is characterized, which also completely establishes all possible combinations of attainable finite p...
متن کاملPartial decoupling of non-minimum phase systems by constant state feedback
Consider an nth order linear time-invariant multivariable system x(i) = A x(t) + B u(t) , y(t) = Cx(t) , (l .l) with the (n, l)-state vector x(t), the (m, l)-input vector u(t), the (m, l)-output vector y(t) and the matrices A, B, C of conformal dimensions. Input-output decoupling is achieved if one can find a constant (m, n)-controller matrix R and a constant (m, m)-prefilter F such that via th...
متن کاملPartial disturbance decoupling problem for structured transfer matrix systems by measurement feedback
Partial disturbance decoupling problems are equivalent to zeroing the first, say k Markov parameters of the closed-loop system between the disturbance and controlled output. One might consider this problem when it is not possible to zero all the Markov parameters which is known as exact disturbance decoupling. Structured transfer matrix systems are linear systems given by transfer matrices of w...

Using the continuous time algorithm given, the optimal is Absfract-This note studies the problem of decoupling in the linear, time invariant, multiinput-multioutput unity-feedback system. A parameterization of all stabilizing decoupling controllers and all achievable decoupled closed-loop transfer functions is obtained for full-row rank plants which do not have any coinciding poles and zeros in...
