“…The paper presents the analysis of control performance versus δ , at the final stage of research on the search of the control law resulting in superior performance, and yet computationally simple enough to be implemented on the STM32 microcontroller, for the considered robot. Earlier papers compared plain LQR to robust LQR approaches (with LQI considered), see [44], analyzed the impact of δ on robust versions of LQR and LQI algorithms, see [31], or the impact of initial condition of x 1 [17 versus δ on similar performance indices as in this paper.…”

“…The results turned the attention of the authors to a problem with lesser DoF to be concerned [32]. First, by introducing robustness into LQR/LQI control laws with results based on experiments [31], then introducing feedback linearization to a simulation model [44], with in-depth analysis of impact of initial conditions and robustness parameter [45], and different linearization schemes [17]. This paper is mainly focused on extending the results referring to the best combination of control approaches at the research stage of [31], when feedback linearization is used, and in the case of possible actuator failure, which mimics uncertainty introduced by the linearization of the robot model, or by possible constraints in the control signal.…”
