Introduction

I. INTRODUCTION

Due to robustness, dependability, and affordability, the induction motor is utilized extensively in numerous industrial applications. Effective control strategies are necessary to achieve precise speed control and maintain stable operation under a variety of operating conditions. Conventional control strategies, like relative vital subsidiary (PID) regulators, have been broadly utilized for enlistment engine control. However, their ability to deal with uncertainties, nonlinearities, and external disturbances may be limited.

Sliding mode control (SMC) has arisen as a promising option for tending to these difficulties. By using a sliding surface to direct the system's trajectory, SMC provides inherent robustness and disturbance rejection capabilities. SMC reduces the impact of uncertainties and disturbances by ensuring that the system's state remains on the sliding surface.

The purpose of this study is to compare the performance of various SMC controllers and PID controllers for controlling induction motors. Three particular sliding surfaces are planned and carried out in the SMC regulators to explore their impact on the framework's way of behaving. The purpose of the selected sliding surfaces is to enhance robustness against parameter variations, reduce chattering, and enhance tracking accuracy.

The exploration procedure includes directing broad reenactments utilizing a high-constancy model of the enlistment engine framework. In order to evaluate the controllers' performance, the motor system is put through a variety of operating conditions, including load disturbances and parameter changes. The advantages and disadvantages of the PID and SMC controllers can be learned by comparing their responses.

Sliding mode control strategies for induction motor control should be better understood as a result of this study's findings. The selection of appropriate control strategies for specific applications will be made easier with the assistance of an analysis of the various sliding surfaces and how they affect controller performance. Additionally, the results of the research will shed light on the trade-offs that exist between PID and SMC controllers, assisting researchers and engineers in making decisions regarding the control design of induction motor systems that are based on accurate information.

In general, the goal of this study is to compare and contrast PID and SMC controllers for induction motor control. This study's findings and insights will aid in the creation of more effective and reliable control strategies for induction motor applications and advance motor control research. admissions in reputed varsity. Now, here we enlist the proven steps to publish the research paper in a journal.

II. MODELLING OF INDUCTION MOTOR

Due to their ease of use, durability, and low price, induction motors are widely used in industrial settings. A mathematical representation of an induction motor's dynamic behavior is needed to model it. The motor system's analysis, control design, and performance evaluation are all made possible by this. One normal methodology for demonstrating an enlistment engine is using state space conditions, which can be changed into an exchange capability portrayal.

Conclusion

This study looked into the design of sliding mode control strategies for controlling speed in an induction motor system. The objective was to evaluate the effectiveness of various sliding mode control strategies in controlling precise speed, resisting parameter changes, rejecting disturbances, and reducing chattering phenomena. The sliding mode control strategy outperformed the conventional PID control method, as evidenced by the obtained results. The sliding mode control strategies demonstrated enhanced capability for disturbance rejection, robustness to parameter variations, and improved speed tracking accuracy this research contributes to the understanding and application of sliding mode control in the context of speed control for induction motors, demonstrating its effectiveness and potential for achieving high-performance control.
