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.

Four tanks

The system of four tanks is one of the most used in the learning of multivariable process control. The system is composed by four tanks. At the bottom of each of them there is an outlet of known section and another one with an unknown section, regulated by means of a valve that enables or disables the corresponding perturbation. The system also has two three-way valves that allow regulating the flow, coming from two pumps, that enters in each one of the tanks.

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.

Heat flow system (advanced)

This device consists on a box equipped with the following components: a heater and a fan placed in one of the extremes of the device and three temperature sensores placed in different points along the box. The power for the heater and the fan velocity are controlled using analogic signals. Temperatures are measured using platinum transductors due to their velocity in the stabilization of the measurements. The advanced version of this lab allows uers to program their own controllers instead of just using the PID implemented in the basic version.

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.

Lamp temperature control

Apply an on/off control in a system with two inputs and one output. The inputs are the state of a lamp (wether it is turned on or off) and the state of a fan (also with on/off positions). The lab allows you to measure and control the temperature in the glass of the lamp while also monitoring the temperature in the room.

Light in isotropic media

The laws of reflection and refraction are studied in this experiment. A stepper motor controls the rotation of a disc to which a laser is fixed. By moving the motor, the laser rotates around a plastic container filled with water and therefore, the angle in which its light incidences over this medium changes. The reflected and refracted rays can be seen with the webcam and a virtual pointer is used to measure the corresponding reflecting and refracting angles.

Mobile robots control

This laboratory is based on a multi-agents system consisting on a group of small wheeled robots (Moway). These robots are composed by five modules: processing system, drive system, sensors and indicators group, power supply system and the expansion connector for radiofrequency wireless communication (RF). The robots can communicate with each other, avoid obstacles and cooperate in a master-slaves architecture.

Photoelectric effect

In this practice, fundamentals of the photoelectric effect are studied and an experimental determination of Planck’s constant, h, is carried out. The lab allows selecting the wavelength of the light that gets to a photoelectric cell, taking measures of the registered stopping voltages and plotting both values (voltages against wavelengths) in order to make a linear regression and obtain h with good precision
