(2023) Sliding surface optimization via regional pole placement for a class of nonlinear systems. In: 2023 27th International Conference on System Theory, Control and Computing (ICSTCC), 11-13 October 2023, Timisoara, Romania979-8-3503-3799-02372-1618https://doi.org/10.1109/ICSTCC59206.2023.10308470https://dspace.lib.cranfield.ac.uk/handle/1826/20568In this paper, a new approach is introduced which combines Eigenvalue Assignment, State Dependent Riccati Equation (SDRE) and Sliding Mode Control (SMC) methods for nonlinear systems. In the classical SDRE based SMC (SDRESMC) approach, a nonlinear system is frozen at each time instant to obtain a linear-like structure model that is used to design a sliding surface (SS) at each time instant. This mechanism produces a state-dependent SS to hold the states on the SS. The approach proposed here is built on this mechanism and offers a new way to design a state-dependent SS for nonlinear systems so that the pointwise eigenvalues of the closed-loop system matrix of the control-free dynamics in the regular form can be kept in a specified disk. This gives a great advantage to shape the transient response characteristics. The performance of the nonlinear controller approach proposed here is investigated in simulations.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/nonlinear systemseigenvalue assignmentsliding mode controlsliding surface designConference paper979-8-3503-3798-3
