Introduction

**Course Review: Controle de Sistemas no Plano-s on Coursera** **Overview:** If you're looking to deepen your understanding of control systems in engineering, the "Controle de Sistemas no Plano-s" course on Coursera is an excellent choice. This course is designed to equip you with the skills to sketch the Root Locus (Lugar Geométrico das Raízes - LGR) of the denominator of a closed-loop transfer function based on the poles and zeros of an open-loop transfer function. By the end of the course, you'll also be capable of designing phase-leading controllers to meet both damping and response speed performance requirements, as well as utilizing phase-lag controllers to satisfy steady-state error criteria. **Syllabus Breakdown:** 1. **Performance Regions and Second-Order Approximation:** This module lays the foundation by introducing you to key concepts and reviewing the step response formulas of underdamped systems. You'll learn about the s-plane (Plano-s) and how to represent performance requirements graphically. The ability to disregard certain poles and zeros in step response under specific conditions is a unique aspect that you'll find particularly insightful. 2. **The Root Locus:** In this module, you will delve into the concept of Root Locus, a graphical technique for analyzing and designing control systems. You'll learn the methodology for sketching the LGR based on the open-loop transfer function, which is crucial for understanding system stability and performance. 3. **Phase-Lead Controller:** Here, you will explore the design of phase-lead controllers (commonly known as lead controllers) to meet performance specifications that conventional proportional control systems cannot achieve. The instructor adeptly introduces the proportional-derivative (PD) controller, enhancing your grasp of the concepts. 4. **Phase-Lag Controller:** The focus shifts to phase-lag controllers, where you'll understand that simply increasing system gain isn't sufficient for meeting steady-state error requirements. This module teaches you how to use phase-lag control strategies without adversely affecting other system performance characteristics, including learning about proportional-integral (PI) controllers. 5. **Lead and Lag Controllers, Transportation Lag:** This module culminates the learning process by teaching you to design lead-lag controllers (combining both phase-lead and phase-lag) and provides insights into PID (Proportional-Integral-Derivative) controller design. Additionally, you'll confront the challenges posed by transportation lag, learning how to effectively manage it using phase-lead controllers. **Recommendation:** I highly recommend "Controle de Sistemas no Plano-s" for students, educators, and industry professionals interested in the field of control systems. The curriculum is thoughtfully structured, providing both theoretical knowledge and practical applications. The detailed modules ensure that you progress at a steady pace while thoroughly understanding each concept before advancing. What sets this course apart is its comprehensive approach to controller design, equipping you with essential tools needed for both academic and professional success in control engineering. The blend of intuitive graphical methods with analytical techniques caters to different learning styles, making the material accessible to a wider audience. In conclusion, if you're keen to enhance your control systems capabilities, this course is a valuable investment in your education and skills development.

Syllabus

Regiões de desempenho e aproximação de segunda ordem

Neste módulo fazemos uma breve introdução incluindo uma revisão sobre as fórmulas da resposta ao degrau de um sistema subamortecido.Você aprenderá o que é o Plano-s e como representar requisitos de desempenho no Plano-s e verá também que em alguns casos podemos desprezar a contribuição de alguns polos e zeros na resposta ao degrau.

Neste módulo você aprenderá o que é o Lugar Geométrico das Raízes, também conhecido como Root Locus e aprenderá também como esboçar o LGR a partir da função de transferência do sistema em malha aberta.

Neste módulo você aprenderá a projetar um controlador de avanço de fase, também conhecido como controlador lead, para atender a requisitos de desempenho que não poderiam ser atendidos com um sistema controle proporcional. Você aprenderá também o que é o controlador PD.

Neste módulo você verá que não pode tentar atender a um requisito de erro em regime permanente simplesmente aumentando o ganho do sistema. Para atender a um requisito de erro em regime sem alterar outras características da resposta do sistema é preciso usar um controlador de atraso de fase. Você também vai aprender o que é um controlador PI.

Neste módulo você vai aprender a projetar controladores de avanço e atraso de fase, ou lead-lag. Você também verá um projeto de controlador PID e aprenderá como lidar com o atraso de transporte usando um controlador de avanço de fase.
