Dynamic Test Rig and Electro-Hydraulic Systems Engineering

UK engineering services for electro-hydraulic actuation, embedded control systems and dynamic test rigs where stability, response, safety and data quality are critical.

Why teams engage PTL for precision control systems

Precision control programmes can display serious shortcomings when deployed in real-world environments. Dynamics become unstable, interfaces behave differently in practice, or rigs fail to generate the data with the accuracy they were designed for.

PTL is engaged to prove controllability early and reduce that risk before hardware decisions are finalised. We typically support programmes from requirements capture and dynamic modelling into hardware and control strategy. From there, we support instrumentation and DAQ planning, commissioning and optimisation using measured data. That approach is shaped by experience in dynamic rig development, fast-response electro-hydraulic systems and model-to-test correlation.

Dynamic rig and electro-hydraulic development

Insightful scrutiny of a hydraulic braking concept

PTL provided clear, insightful technical scrutiny of our novel hydraulic braking concept, helping us identify the key engineering risks and priorities at an early stage. Their experience-based assessment gave us confidence in where to focus development effort before committing to detailed design.

CASE STUDY

Building a Dynamic of Trusted Bearing Validation Data

PTL developed a dynamic bearing test rig in collaboration with Southwest Research Institute capable of recreating fast-changing loads and generating reliable validation data. The project linked rig design, hydraulics, controls and measurement into a more credible route for bearing development, lubrication analysis and model correlation.

CASE STUDY

Development of Integrated In-Wheel Unit Including Motor and CVT Transmission

PTL carried out concept studies for the control of an eBike with CVT transmission, in-wheel motor and wider electrical system development. Control accuracy was essential for a good rider experience. The work helped clarify what was technically viable before greater time and cost were committed.

Frequently asked questions
about test rig and control engineering

Yes. PTL designs dynamic test rigs including electro-hydraulic and motorised systems, with instrumentation, data acquisition and controls integrated from the outset. Typical applications include bearing test rigs, actuator test stands, endurance rigs and bespoke research platforms.

Recent rig programmes have involved dynamic loading capability up to approximately 400kN with controlled load response times around 6ms. Specific capabilities are always shaped around the programme, with measurement quality and repeatability as the guiding constraints.

Yes. PTL supports embedded control systems, electronics, sensors and software across motor controllers, inverters, data loggers, firmware, schematic capture, PCB layout and prototype manufacture.

Model-to-test correlation is a core part of PTL’s precision control work. We build dynamic models alongside the rig, then use measured data to correlate, refine and validate. This gives clients trusted data rather than separate model and hardware worlds.
