REX Controls is a SME focused on performing advanced control algorithms and its own cost control system REX which is compatible with a global standard Matlab Simulink but is not dependent on Matlab.
REX is suitable for rapid development of embedded control systems on different hardware platforms (PCs, Industrial PCs, single board computers, programmable automation controllers, ARM based microcontrollers) and operating systems (Windows, Windows CE, Linux, Linux/Xenomai, Free RTOS).
REX implements more than 200 various function blocks in a large function block library. Besides standard math blocks and other simple blocks the library contains advanced sub-libraries covering the following topics:
- PID control including built-in autotuning algorithms
- Predictive control and Sliding mode control for nonlinear/nonsymetric systems (e.g. heating-cooling systems)
- Motion control (PLCopen compatible)
- Active vibration damping feedback controllers and feedforward shaping filters
- Sequential control (SFC compatible)
- Simulation blocks (for Hardware-in-the-loop simulations)
- Alarm and trend blocks
REX based control systems communicate with outer world via input/output drivers for the following communication protocols or direct I/O boards:
- EtherCAT
- Ethernet POWERLINK
- CAN/CANopen
- Modbus RTU and TCP/IP
- OPC client and server
- driver for direct I/O boards by Advantech
The shortest real-time control period can be about 100 microseconds (depends on selected input/output driver).
REX control algorithms are broadly used by Czech and German automation companies in their PLCs,
PACs and compact controllers – Teco a.s., ZAT a.s., PMA GmbH to mention a few. Through these companies they are distributed to the end customers. For example our control loop tuning software is used by Daimler Chrysler, Volkswagen, AREVA, Sony, Robert Bosch, Max-Planck-Institut Köln. REX Controls has experience in development control strategies for various technologies including plastic extruders, advanced textile machines, experimental nuclear reactor, 800-tons coal mine walking pontoon, steam turbines, water power plants, mechatronics devices and robots.
