The calculation of mixed-sensitivity H-infinity control is proven scientifically in this work for the DC motor plant experiment. Although the proposed design has significant higher order, it can easily improve DC motor speed control through personal computer (PC)-based control. In addition, the Lyapunov stability assessment on eigenvalues and graphical method proves that the proposed controller design is asymptotically stable. The robustness performance improves significantly because the proposed plan has better overshoot errors and smother signal. The optimization controller design is robustly stable due to loaded mass as disturbance assessment. The proposed controller’s singular values are successfully dropped significantly twice due to robustness improvement from the experimental data. Comparison of theoretical modeling of mechatronics principle and experimental identification model is used for finding the best plant model to be processed by mixed-sensitivity synthesis. This research aims to improve the robustness of DC motor speed control by H-infinity optimization of mixed-sensitivity synthesis technique to deal with uncertainty and disturbance.
Robustness is an essential criterion for DC motor applications, from electronic household appliances to electric vehicles. The performance of the DC motor is related to its stability and accuracy, which becomes a robust control goal. Overload and accident have the possibility to be a significant disturbance. The uncertainty may occur because of mechatronic component degradation, sensor noise, and environmental effect. Speed control of DC motor needs excellent robustness to guarantee its function to work properly against uncertainty and disturbance. Predictive nonlinear optimal control (PNOC) is employed to eliminate torque ripple and improve system stability.

MATLAB software is utilized to construct the simulation of the control circuit, and simulation outputs are validated by experimental findings. The generated model is subjected to simulations under both healthy and incorrect settings, respectively. PNOC is a driving system that uses predictive nonlinear optimal control (PNOC). The purpose of this essay is to integrate these two technologies in order to make contributions via the development of a new hybrid EEC-FDL model closed-loop brushless DC motor. Despite numerical methodologies, these approach scenarios give frequency domain loop (FDL) precision frequency domain, using a suitable weight strategy to deliver high power solution creation (NM). It is possible to model a machine using many existing technologies, such as electrical equivalent circuit diagram (EEC), which are based on a number of assumptions that make the analysis process or the analysis approach simpler. The project manager should have a thorough discussion with the team about the demagnetization of the malfunctioning BLDC motor before beginning this job. The BLDC drive controls the motor via the converter circuit, and the converter circuit ensures that the motor receives the appropriate output power. In this motor, the movable component of the rotor created torque and the rotor rotated in a position of low reluctance the location of the rotor is determined by the motor’s maximum inductance value. A BLDC is a kind of electric motor that is used in a variety of applications and is one of the models of electric motors that are utilized in constant speed applications. Using predictive nonlinear optimal control, this model examines the output power of a three-phase brushless DC motor (BLDC) drive to ensure that it is stabilized (PNOC).
