24 de feb. de 2021 · Plant block is shown with the uncertain transfer function in which two values in the denominator coefficients are unknown. The scope block is giving the output signal. The reference tracking specification block is plotting the model and giving the optimization option.
3 de jul. de 2020 · We depict the performance of obtained robust controllers with step responses, control variables, load disturbances and external noise in a post-processing analysis. We also illustrate the robustness of the obtained controllers with probability density functions and cumulative distribution functions of objective functions for ...
1 de sept. de 2000 · In this paper, the Kharitonov theorem for interval plants is exploited for the purpose of synthesizing a stabilizing controller. The aim here is to develop a controller to simultaneously stabilize the four Kharitonov-defined vortex polynomials.
The step responses across the Parray family are consistent with a closed-loop bandwidth of 8 rad/s. Using desBW = 20 yields a poor design with robust performance muPerf of 1.35. This is expected because this target bandwidth is in the vicinity of very large plant uncertainty.
1 de jul. de 1993 · Design Fl (s) so that a robust non-overshooting step response is possible for all plants in the uncertain plant set. This can be done by properly placing the closed loop poles and the zeros so that all dominant closed loop pole-zero configurations satisfy Theorem 3.
Robust Controller Design. This example shows how to design a feedback controller for a plant with uncertain parameters and uncertain model dynamics. The goals of the controller design are good steady-state tracking and disturbance-rejection properties.
Plot the step response of the plant and closed-loop system. The step command automatically generates 20 random samples of the uncertain parameters gamma and tau and plots the corresponding step responses.
