This laboratory represents the lower level in the production and technological processes control. It involves collecting and processing information from the technological process as well as the control algorithms utilising programmable logic controllers or industrial regulators able to communicate with superior system of higher level. The laboratory contains the parts shared among individual workplaces (internal electricity distribution including circuit-breakers, Ethernet wiring including corresponding active and passive components, data bus network, signal distribution systems, and connection of external signal sources), and working stations.
For modelling, controlling and optimising the systems and processes where the mathematical model object of control does not exist, or eventually it cannot be set or the way of setting it is unknown, we offer the solution via progressive methods of modelling, controling and optimising using fuzzy modelling and control, utilisation of neural networks and optimisation genetic algorithms. In case of knowing the processes explicitly, i tis possible to use knowledge and expert systems.
The laboratory comprises the following workplaces:
a) Research workplaces for complex processes
The workstation includes the models and components described below:
- Hybrid production system
Physical model of hybrid production system connecting elements of process and industrial automation. The model enables simulating complex operations and processes occurring in food, chemical and pharmaceuticla enterprises.
- Model of communicating vessels
The equipment consists of five identical laboratory model sused to simulate technological processes from the field of process automation and to perform the field related experiments.
b) Research workplaces for development and design of control systems
The system contains software tools for computer aided design and production documentation of automated control systems. Hardware components and work panels for simulating and testing the designed and projected solutions, as well as server with input/output cards enabling simulation of various technological processes are also a part of the workplace. Real control tool inputs and outputs are supplied with real signals of simulated processes obtained using a terminal block.
Decentralised control system (DCS), another part of the workplace, is composed of industrial control systems, engineering, human-machine, maintenance systems and of other sub-systems and modules listed below.
c) Research workplace for modelling and simulation of technological processes
The workplace includes software tools and models serving for:
- multi-domain simulation and model-oriented design in the field of dynamical and interconnected systems - utilising the interactive environment and adjustable set of basic block libraries
- using the commonly used algorithms in solving both standard and large-scale optimisation tasks - utilising functions for linear programming, quadratic programming, binary integer programming, non-linear optimisation, non-linear least squares, system of non-linear equations, or multi-criteria optimisation..
- searching global solutions for multiple extreme problems
- designing, implementing, visualising and simulating neural networks if teh use of formal analysisi is considrede difficult, or impossible, e. g. pattern recognition, non-linear system identification, and control
- solving and handling the symbolic mathematical expressions and performing variable precision calculations. Connected to the module No. 1, it allows solving tasks involving differentiation, integration, simplification, transformation, and solving equations
- modelling and and simulating physical systems involving mechanical, electrical, hydraulic, and other physical domains
- simulating three-dimensional mechanical systems such as robots, axle suspension system of vehicles, construction equipment, and plane bogies.
Research activities in the field of mathematical modelling and numerical simulation of dynamic systems are focused on solving linear and non-linear tasks in the field of control theory using modern, sophisticated tools of differential equations theory, theory of dynamic systems and numerical analysis.
The equippment of the research workplace is complemented by three robots on which non-standard collisions and accidents of robotic workplaces are simulated as well as the optimisation o f their control.
d) PCS7 Distributed Control System
The system contains software means for computer-aided design and development of autmated control systems documentation. The system comprises also hardware components and working panels for simulating and testing the designed and projected solutions as well as it contains a server with input-output cards which due to its software tools allows simulating of different technological processes. Real signals from simulated proceses are are brought to inputs and outputs of real control means by a connecting distributor.
Another part of the workplace is represented by a decentralised control system (DCS) composed of industrial controlsystems, engineering, human-machine, maintenance systems and of other subsystems and moduels. The system will be determined for the research and development of homogenous and heterogenous tasks of automation and control for all industrial fields using various technological and software approaches (focused mainly on joint processes.
