Robust Liquid Level Control of Quadruple Tank System: A Nonlinear Model-Free Approach

Actuators, 2023
In this paper, two new versions of modified active disturbance rejection control (MADRC) are proposed to stabilize a nonlinear quadruple tank system and control the water levels of the lower two tanks in the presence of exogenous disturbances, parameter ...

Kernel Minimum Error Entropy Based Estimator for MIMO Radar in Non-Gaussian Clutter

IEEE Access, 2021
In this paper, a kernel minimum error entropy (KMEE) based estimator is proposed for the estimation of multiple targets’ direction of departure (DOD), the direction of arrival (DOA), and the Doppler shift with multiple input multiple output radar ...

An application of modified sigmoid function to a class of $q-$ starlike and $q-$ convex analytic error functions

Turkish Journal of Mathematics, 2022
In this study, in the open unit disc $\Lambda$, by applying the $q-$ derivative operator and the fractional $q-$ derivative operator and by using the principle of subordination between analytic functions, we introduce some new interesting subclasses of $q-$ starlike and $q-$ convex analytic functions associated with error functions and modified sigmoid

The Modified Trapezoidal Rule for Computing Hypersingular Integral on Interval

Journal of Applied Mathematics, 2013
The modified trapezoidal rule for the computation of hypersingular integrals in boundary element methods is discussed. When the special function of the error functional equals zero, the convergence rate is one order higher than the general case.

Improved active disturbance rejection speed control for autonomous driving of high-speed train based on feedforward compensation

Science Progress, 2023
Due to the complex and changeable train operation environment and the unstable and time-varying parameters, accurate modeling is limited. Therefore, a modified active disturbance rejection control algorithm based on feedforward compensation (FC-MADRC) is
