Question: Design a Luenberger observer using Ackermann’s formula assuming that the output θa (t) is the only measurement. You can derive it using the 4 bar linkage diagram on the front ( tie rod, steering arm) by keeping the outer angle greater than inner. This should give you a relation between the front trackwidth, steering arm and the angles of tires. The contention is with positive ackermann angles and the ones that suit best.State-Feedback Control. One of the advantages of state space models is that it is possible to apply state feedback to place the closed loop poles into any desired positions. 8.2.1. State Space Design Methodology.
