Pole Placement Controller Design for Linear Parameter Varying Plants

Nonlinear plants can often be modelled as linear parameter varying (LPV) plants for which a number of techniques exist for control synthesis. However, there are some systems for which such a technique presents difficulties. In this paper, we consider one such system for which we propose a pole placement method using state feedback in order to cancel parameters variation of LPV plants. Hence, any linear time invariant (LTI) controller can subsequently be employed for an outer loop. The approach is demonstrated on an example for which only a single output can be measured. Therefore, a state observer for an LPV plant is also demonstrated in order to estimate state values. The simulation results show that the new approach yields reliable closed-loop stability with good closed-loop transient performance of the system. 
