Signals and Mechatronic Systems

Objectives

Theoretical and laboratorial instruction in modelling and performance analysis, in time and frequency, of dynamical systems continuous in time.

Program

Analog signals. Static, dynamic and deterministic systems. Laplace and Fourier transforms. Representation of SISO systems as a transfer function. Modeling of dynamic systems such as energy converters: flow, potential, accumulators, sinks. Application to mechanical, electrical, fluidic and thermal systems: analogies between systems. Block diagram algebra. Analysis of first-order, second-order, zero-zero, higher-order, non-minimum-phase, stable and unstable dynamical systems, and system reduction. Routh-Hurwitz stability criterion. Responses in time: impulse, step, ramp. Frequency responses: Bode and polar plots. Position, velocity, acceleration, proximity, force, torque, flow, level, temperature sensors. Actuators in a control ring: servomotors and pneumatic actuators. Linearization and operating point. Chain of action and chain of measurement. AD/DA conversion. Filters and signal conditioning.

Teaching Methodologies

The teaching structure of the subject consists of 42 hours of theory and 14 hours of laboratory practice. Thus, it is intended to create a dynamic and interactive learning environment, based on an organized structure of reasoning. The classes will be of theoretical development, based on the base bibliography of the discipline, using reference examples that allow to support the inherent laboratory practice.
