Investigation of closed-loop dynamic responses using Rectilinear and Torsional Apparatuses

Mechanical systems are generally classified as open-loop and closed-loop systems according to their architecture. The open-loop systems are driven by externally applied forces and moments with pre-programmed dependence on time. The closed-loop systems apply the feedback control principle based on sensing system motion parameters.

The algorithms describing how to generate feedback signals are called controllers. In this assignment you will learn and test the most popular controller used in industry, which is called Proportional-Integral-Derivative "PID" controller. Using dynamic system transfer function you will analyse transient dynamics of this system and also study feedback control strategies allowing mechanical system to behave accordingly to prescribed control input. Mechanical or robotic system architecture typically includes simple mechanisms executing either rectilinear or rotational motion.

The main objective of this experimental work and assignment is to understand behavior and to learn basic dynamical properties of a simple mass-spring-damper system (ECP-210) and a rotating disk (ECP-205) under action of externally applied force and torque, respectively.

The external driving force or torque can be formed as a predefined function of time allowing you to understand different aspects of their dynamics and compare the observations with related mathematical models.

You will be asked to draw conclusions from your experimental study and confirm them using theoretical analysis.

Outline

Abstract
The abstract should summarise the whole report

I Introduction
Introducing control systems with examples
Introducing two experimental systems (Rectilinear and Torsional Apparatuses)
Potential applications for investigated two systems

II System modelling
Rectilinear system modelling (principle, differential equation, transfer function)
Torsional systemmodelling(principle, differential equation, transfer function)

III Experiments
Proportional-based position control for rectilinear system
PID-based position control for rectilinear system
Proportional-based control for torsional system
PD-based position control for torsional system
Remark: why we use PD controller for position control rather than PID?
Speed control for torsional system

IV Discussion
How the PID parameters affect the system performance?
Why the experimental results are slightly different from theoretical results?

V Conclusion and Future work
Conclusion should recall all the materials in the report briefly
Future work is an open question. Please prospect the research and applications

Reference
Please cite some references which support your statement or scenario as evidence.
