A Discrete-time Linearization Feedback Control for Nonlinear Continuous-time Systems

This paper proposes a linearization feedback method resilient to structural alterations arising from discretization, thereby elevating controller efficacy during the discretization process. The proposed method employs the least-squares method to derive the feedback law in a straightforward manner. Extensive numerical simulations validate that the proposed method exhibits comparable performance to the continuoustime-defined method in terms of response and error. Moreover, the study confirms that adhering to a specific discretization method improves controller performance. Consequently, the proposed method is deemed effective
