Solution by Steps
step 1
To identify the state-space model of the MIMO system, we can represent the system in the form:
x˙(t)=Ax(t)+Bu(t)
where A is the system matrix, B is the input matrix, and u(t) is the input vector. The outputs are given as y1=x1 and y2=x2
step 2
To check the stability of the system, we need to find the eigenvalues of the matrix A. The system is stable if all eigenvalues have negative real parts. This can be done by calculating the characteristic polynomial and finding its roots
step 3
The state-transition matrix Φ(t) for a continuous-time system can be computed using the formula:
Φ(t)=eAt
This matrix describes the evolution of the state over time
step 4
To find the state x(t) given a unit step input and initial conditions x(0)=[10], we can use the formula:
x(t)=Φ(t)x(0)+∫0tΦ(t−τ)Bu(τ)dτ
where u(t) is the unit step function
Answer
The state-space model, stability check, state-transition matrix, and state x(t) can be derived as described in the steps above.
Key Concept
The state-space representation is a mathematical model of a physical system that describes its dynamics using state variables.
Explanation
The solution involves identifying the state-space model, checking stability through eigenvalues, calculating the state-transition matrix, and determining the state response to a unit step input.
