“…The separation principle of the linear system allows the observer and the controller to be designed separately, which facilitates the design of the system [36]. But for nonlinear systems, this separation principle does not necessarily hold [37–39]. In this paper, the separation principle is extended to quasi‐linear systems, and the validity of the separation principle for quasi‐systems is demonstrated.…”

This paper designs an observer‐based feedback controller for quasi‐linear systems when the entire state vector is unavailable for measurement. First, based on the solution of a type of generalised Sylvester equations, general complete parameterisation of the full‐order observer is proposed. Second, the traditional separation principle is applied to the quasi‐linear systems. In other words, the design of a state feedback and the design of a state observer can be carried out independently. Further, general complete parameterisation of the state feedback controller is also established. Finally, numerical examples and simulations are adopted to verify the effectiveness of the proposed method.
