Control unit of pneumatic system
The work is dedicated to the design and implementation of the pneumatic system control unit. The pneumatic system consists of wind tunnel with two fans. The first fan blows air into the wind tunnel, and the air spins the second fan. The control unit is complemented by a measurement system that measures the rotation speed of both fans. The control unit also provides PWM signal to control the first fan power, communication with the control panel including LCD displays, generating a measurement signal for an external controller and enables communication via USB.
 
Simulator of dynamical systems on the AMiNI4DS
The aim of this work is to develop a set of programs for the control system AMiNi4DS to simulate different dynamic SISO systems. Inputs and outputs of a mathematical model will be connected to the voltage inputs and outputs of the control system. The mathematical model is implemented as a discrete state with the minimum achievable sampling period. Programs for AMiNi4DS will allow the display of actual voltage inputs and outputs on the LCD display. A set of programs will be created in program DetStudio. Entering specific systems with a choice of order will be realized using the GUI in MATLAB. Dynamic systems in MATLAB will be insterted in the form of a continuous description.
