Active Disturbance Rejection Control Design With Suppression of Sensor Noise Effects in Application to DC–DC Buck Power Converter

نویسندگان

چکیده

The performance of active disturbance rejection control (ADRC) algorithms can be limited in practice by high-frequency measurement noise. In this article, problem is addressed transforming the high-gain extended state observer (ESO), which inherent element ADRC, into a new cascade structure. Set experiments, performed on dc–dc buck power converter system, show that ESO design, compared to conventional approach, effectively suppresses detrimental effect sensor noise overamplification while increasing estimation/control performance. proposed design also analyzed with low-pass filter at output, common technique for reducing industrial applications.

On the robust linear control of the "buck-buck" converter: An active disturbance rejection approach

In this article, the cascade connection of two “buck” converters is examined from the perspective of differential flatness and Generalized Proportional Integral (GPI) observer–based control. The multi-variable nonlinear “buckbuck” converter is subject to unknown, time-varying, load current demands, at each one of the outputs of the two constitutive stages. The linear output feedback controllers...

Application of Linear Active Disturbance Rejection Control to Power System Load Frequency Control

In this paper, linear active disturbance rejection control (LADRC) is employed to deal with the load frequency control (LFC) problem in power systems with a single generator supplying power to a single service area. First, the general (n+1)th order LADRC is given, and then the parameter tuning procedures are presented. It is followed by the description of an LFC problem, in which the case of a ...

387g Active Disturbance Rejection Control (Adrc) - Application to Nonlinear Cstr

Zhongzhou Chen, Sridhar Ungarala, and Zhiqiang Gao In recent years significant research has focused on process control strategies which rely heavily on process models. Generally, it takes a great deal of effort to obtain an accurate dynamic model, especially if the process is nonlinear. The task of modeling and prediction is also compounded by model parameters subject to changes over time and u...

Designing a novel structure of explicit model predictive control with application in a buck converter system

This paper proposes a novel structure of model predictive control algorithm for piecewise affine systems as a particular class of hybrid systems. Due to the time consuming and computational complexity of online optimization problem in MPC algorithm, the explicit form of MPC which is called Explicit MPC (EMPC) is applied in order to control of buck converter. Since the EMPC solves the optimizati...

Voltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control

Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent.  This controller is used in a double loop structure including an inner current loop and oute...
