Controle por realimentação de estado de um motor CC

Abstract

This work aims to develop a speed control system for a direct current (DC) motor using state feedback. The specific objectives include modelling the motor via transfer function and state-space representation, designing a controller, performing simulations, and comparing different system responses. The justification is based on the use of control theory to create precise mathematical models that optimize the performance of DC motors, thereby improving energy efficiency and extending their lifespan. The state feedback technique is used, allowing speed control without the need for direct measurement sensors, which reduces costs and simplifies implementation. The research developed and validated a controller capable of eliminating steady-state error, using the input voltage as the control variable. The work also suggests future improvements, such as the implementation of a state observer to meet the needs of systems with higher demands. Additionally, the results can be applied in educational contexts, providing an accessible study for both beginners and students of modern control theory.
