SUPPORT SERVICES- CONTROL SYSTEMS
This is our control systems Heading
Servo Control
Comar have over 20 years' experience with our electronic control system partners ,in single and multi-channel closed loop servo-hydraulic control systems. Typical systems have incorporated closed loop control of position, speed, load, torque and pressure. Profiling of the closed loop gains against control variables is achieved through look up tables in the real time embedded controller.
Profiles are edited and stored on the user interface PC and downloaded to the embedded controller prior to running the test rig. The servo control system is digital, so we are able to vary the PID terms of the controller to
cope with extreme cases of static and dynamic operation. Customised algorithms are developed and optimised in the servo controller to eliminate the effect of any non-linearities found in the rig or unit under test.
Our servo control systems interface to the standard range of instrumentation equipment ranging from load cells, torque transducers, pressure transducers, flow meters, tachometers, temperature transducers, rotary and linear position transducers including LVDTs, RVDTs, VRVTs and encoders.
Our strong alliance with Comar has produced a large number of rigs from a few “kgs” to complex electro/hydraulic control systems of many “tonnes”. CCS have provided the software and electronics on many of these systems and this is integrated expertly with Comars’ extensive skills in rig design, modelling, fabrication and installation worldwide to satisfy the most demanding Aerospace criteria
Data Acquisition
The real-time acquisition system is designed to provide simple but flexible data acquisition combined with the unique ability to capture and analyse data in parallel. The user interface has an easy to follow ‘Acquire’ -> ‘Analyse’ -> ‘Report’ structure that has proved very reliable for our clients in the aerospace industries.
Functionality:-
- High-speed logging and triggering (up to 100kHz).
- Automatic / Manual logging.
- Up to 96 analogue inputs and 64 thermocouple channels simultaneously.
- View data live.
- Real-time floating digital panel meters and temperature gauges.
- Analyse data in parallel to logging.
- Overlay channels from other files for comparison.
- Distance and gradient measurements between Euclidean points.
- Create data view templates to rapidly reproduce analysis and report templates.
- One-touch report creation of analysis.
- No need for separate hardware, this is ready to use ‘out-of-the-box’.
- Ethernet connection.
- Hi-resolution monitor.
Unit mounted on heavy-duty, braked, castors for ease of transport and static operation.
If greater portability is required, we can offer the entire system enclosed into a durable flight case as detailed below with no reduction in functionality.
The enclosed system can run exactly the same software on a laptop which is connected to the chassis via Ethernet; this enables the system to run in exactly the same manner as the floor standing model but with the added advantage of worldwide portability.The case itself is extremely hard wearing, more than capable of withstanding the conditions in an aircraft hold and, when fully closed, will suffer no damage if it is left on a luggage conveyor in the rain!
