Assume that the state measurements are not available. Set the input of the system as a low-frequency sinusoidal function. Select a non-zero initial condition for the system. Design a full-order state observer. Set the initial condition of the observer to zero. Explain your logic for selecting the eigenvalues of the observer. Provide the details to design the observer gain, L, using Bass-Gura or Ackermann formula. Plot the estimation error of state variables versus time. Discuss your observations about the transient performance of the state observer and their connection to your selected eigenvalues.
