Chemical processes are usually designed to work under a specified set of conditions; therefore the first goal of a regulatory control scheme is to keep the controlled variable at or near these conditions in the presence ...

Disturbance rejection strategies are very useful for the robustness improvement of the predictive control method. But they can only be used in the modulated-based predictive control methods such as continuous set model ...

This paper presents the analysis of fractional adaptive systems in the presence of bounded disturbances and parameter variations. Fractional adaptive systems are analyzed using the error model approach, to give generality ...

A simple control strategy was studied for harmonic disturbance rejection in magnetic field compensation systems for low-field magnetic resonance techniques. The strategy is based on the simultaneous action of a conventional ...

To impart disturbance rejection properties is an important goal in the design of an appropriate process control structure. In a multivariable control system, the effectiveness of disturbance rejection can depend strongly ...

Abstract. Wind turbines are complex nonlinear machines whose main objective is to convert the wind energy into electric power. These systems work in two main operating regions. In region 2, the energy captured must be ...

The tracking/rejection of periodic disturbances in linear systems is achievable via internal model principle-based techniques, such as repetitive control. However, when the frequency of the signal to track/reject is uncertain ...

This master thesis proposes a current control technique based on sliding mode strategy and disturbance observer for high-performance drive applied to permanent magnet synchronous motors and can be extended to other ...

Even though employed widely in industrial practice, the popular proportional?integral?derivative (PID) controller has weaknesses that limit its achievable performance. In this paper, an alternative control scheme that ...
