Requirements: a, a test to determine the state feedback matrix K, for the output of the phase transition process unit step reference input, to meet the expectations of the following indicators: overshoot σ < 20 , peak time t_p < 0.4s. b, if in fact the system state variables can not be measured, determine a state observer (full-dimensional), so that by the state observer based state feedback, satisfying the above desired performance metrics.
