Math Problem Statement

The problem describes a linear control system with the following state-space equations: dx/dt = A x(t) + B u(t), y(t) = C x(t), where A, B, and C are matrices. The task is to investigate the controllability and observability of the system, and if it is controllable, construct a control law that drives the system from state (0, x(0)) to state (1, 0).

Solution

This image presents a problem about controllability and observability of a linear control system, represented by the following state-space equations:

dxdt=Ax(t)+Bu(t)\frac{dx}{dt} = A x(t) + B u(t) y(t)=Cx(t)y(t) = C x(t)

Where the matrices are given as:

A=(0100),B=(01),C=(10)A = \begin{pmatrix} 0 & -1 \\ 0 & 0 \end{pmatrix}, \quad B = \begin{pmatrix} 0 \\ 1 \end{pmatrix}, \quad C = \begin{pmatrix} -1 & 0 \end{pmatrix}

The task is to study the controllability and observability of the system, and if the system is controllable, to construct one of the many control laws that drives the system from state (0,x(0))(0, x(0)) to state (1,0)(1, 0).

  2. How can we calculate the controllability matrix for a system?
  3. How can we compute the observability matrix for a given system?
  4. What is the role of the input matrix BB in controlling the system?
  5. How do control laws help in state stabilization and system performance?

Tip: To assess controllability, we typically use the controllability matrix, and for observability, the observability matrix.
