Coupled Electric Drives

Practice title:
Tension and velocity control of a belt on a two coupled electric drives system
The device has two electric drives, coupled by means of a flexible belt. The belt passes through a pulley with a system that allows measuring its velocity and tension. The main control problem is to change the torque in the two motors in order to regulate the tension and the velocity of the belt. This can be done either individually or simultaneously. With this laboratory you can perform, among others, these tasks and activities: 
                    • Independent control of the velocity and tension of the belt.
                    • Simultaneous control of the velocity and tension of the belt.
                    • Practical methods for the multivariable control of electromechanical systems.

Ball and Hoop

Practice title:
Control of the ball and hoop system
The Ball and Hoop system is an electromechanical device consisting of a ball rolling on the rim of a hoop. The hoop is mounted on the shaft of a servomotor and can rotate about its axis. The rotation of the hoop causes an oscillatory movement of the ball around its equilibrium point. The behavior of the ball is similar to the dynamic of a liquid inside a cylindrical container. The main objective of this system is to control these oscillations. With this laboratory you can perform, among others, these tasks and activities: 
                    • Study the transmission zeroes and non-minimum phase behaviors.
                    • Velocity and position control of the hoop.

Ball and Beam

Practice title:
Control of the ball and beam system
The system consists of two different subsystems: the ball and beam itself and a motor with a gear wheel, which is connected to the first module through a level arm. The beam consists of a steel rod in parallel with a nickel-chromium wire-wound resistor forming the track on which the ball is free to roll. Measuring the voltage in the steel rod provides the position of the ball in the beam. The control objective of this system is to move the ball to the desired position in the beam. For this purpose, two measurements are taken (the position of the ball and the angle of the motor), and the control signal is applied to the motor. With this laboratory you can perform, among others, these tasks and activities: 
                    • Study of the dynamics of the system.
                    • Study and the design of a control system for the position of the ball.

Furuta Pendulum

Practice title:
Nonlinear control of a Furuta pendulum
The Furuta pendulum is a device consisting of an inverted pendulum pivoting on a rotating base. The turn of this base allows to control the position of the pivot and thus indirectly the angle of the pendulum. This is a challenging device because is unstable (with the pendulum in the upwards position) and it also exhibits non minimum phase behavior. The objective of the practice is to develop a nonlinear control strategy that is divided in two steps: 
                    • Develop a control law that keeps the pendulum on an upwards position while the pivot of the pendulum follows a reference signal. This control law is based on linearization around the unstable equilibrium point.
                    • Implement a swing up control that is able to lift the pendulum from its stable equilibrium position (downwards) to its unstable equilibrium point (upwards) in order to apply the control developed on the previous step.

Flexible Link

Practice title:
Position and vibration suppression control of a flexible link
The Rotary Flexible Link module consists of a thin stainless steel flexible link with one end free, and a DC motor used to rotate the link from the other end in the horizontal plane. The main control problem is the position control of the tip, supressing or minimizing the vibrations that appear due the the elasticity of the link. The built-in sensors of the module provide the position and velocity of the DC motor, and the deflection of the tip. The control variable is the input voltage of the motor. With this laboratory you can perform, among others, these tasks and activities: 
                    • Position control with a PID controller.
                    • Position control with a state-feedback controller and LQR control.

Inverted Pendulum

Practice title:
Control of an inverted pendulum
The rotary inverted pendulum consists of a motor which has a rotary arm attached that can move free 360º. The pendulum is connected at the end of the rotary arm and it can oscillate freely and perpendicularly to the rotary arm. The main characteristics that make it an interesting case of study are that it is a strongly nonlinear, unstable, non minimum-phase, and underactuated system. With this laboratory you can perform, among others, these tasks and activities: 
                    • Nonlinear control to swing-up the pendulum from the stable equilibrium point to the unstable equilibrium point.
                    • Linear control to stabilize the pendulum in the unstable equilibrium point.
