Questões sobre o Capítulo 3 do Livro Texto da Disciplina.

Chapter 3  - State Variable Models - System modeling using time-domain methods. Consider physical systems described by an nth-order ordinary differential equation. Utilizing a (nonunique) set of variables, known as state variables, we can obtain a set of first-order differential equations. We group these first-order equations using a compact matrix notation in a model known as the state variable model. The relationship between signal-flow graph models and state variable models will be investigated..

Questões sobre o Capítulo 4 do Livro Texto da Disciplina.

Chapter 4 - Feedback Control System Characteristics - In this chapter, we explore the role of error signals to characterize feedback control system performance, including the reduction of sensitivity to model uncertainties, disturbance rejection, measurement noise attenuation, steady-state errors, and transient response characteristics. The error signal is employed in the feedback control system via negative feedback. We discuss the sensitivity of a system to parameter changes, since it is desirable to minimize the effects of parameter variations and uncertainties. We also wish to diminish the effect of unwanted disturbances and measurement noise on the ability of the system to track a desired input. We then describe the transient and steady-state performance of a feedback system and show how this performance can be readily improved with feedback.

Questões sobre o Capítulo 5 do Livro Texto da Disciplina.

Chapter 5 - The Performance of Feedback Control Systems - The ability to adjust the transient and steady-state response of a control system is a beneficial outcome of the design of control systems. In this chapter, we introduce the time-domain performance specifications and use key input signals to test the response of the control system. The correlation between the system performance and the location of the transfer function poles and zeros is discussed. We develop relationships between the performance specifications and the natural frequency and damping ratio for second-order systems. Relying on the notion of dominant poles, we can extrapolate the ideas associated with second-order systems to those of higher order. The concept of a performance index is also considered. We present a set of quantitative performance indices that adequately represent the performance of the control system. ​​​​​​​
