Improving Performance Through Understanding and Application of Control Technologies



We provide control engineering consultancy services and training courses.

Control Engineering Consultancy

We can help you develop effective feedback control strategies and assess a whole process including effects on neighbouring/coupled systems and processes. Control objectives, disturbances, nonlinearities, uncertainties, robustness and noise immunity are all considered when a control strategy is developed. Solutions can range from simple classical feedback or feedforward to advanced control, such as model-based methods like MPC or methods like Fuzzy Logic control. However, simplicity is a key objective in our solutions, providing performance criteria can be met.

An in-depth understanding of control technologies together with first-hand experience in diverse industrial applications uniquely positions us to deliver exceptional value to our clients.

Simulation Development

Many of our projects involve the development of high-fidelity and properly validated models, derived from first principles or plant data. This enables "what-if" questions to be asked and allows a new control solution to be compared against the existing to quantify benefits before deploying with confidence.

Our engineers utilise a wide variety of modelling packages such as MATLAB/Simulink, LabVIEW and CD&SIM Toolkit, and Hysys. We can also undertake re-coding of legacy models into new modelling packages, including model conversion from Simulink to LabVIEW.

Software Engineering

Our in-house expertise comes to the fore when an embedded control, signal processing or data acquisition application needs to be turned into reality.

Designs can be implemented as real time applications using LabVIEW and CompactRIO. Our engineers follow proven software design steps of specification, design, implementation, test and deployment, and include software quality plans and extensive documentation.

We can undertake development of bespoke algorithms and tools for control or data processing to meet your company specific needs. Software can be developed in a variety of languages including C/C++, MATLAB, LabVIEW. As an NI Alliance Partner, ISC has staff certified in using LabVIEW.

ISC Ltd is grateful for the support from NXP Semiconductors on a project to develop a vehicle Energy Management System (EMS) based on Model Predictive Control (MPC). It included Processor-In-the-Loop (PIL) testing to demonstrate the attractive performance of the EMS. This is a crucial part of Hybrid Electric Vehicles (HEVs), needed to optimize the combination of the electric motors and combustion engine in hybrid powertrains. It exploits advances in convex optimisation to reduce battery degradation and consumption, to improve the range of a HEV.

Dive Control Simulator

Saturation Dive Supervisor Training Simulator (DCS)

ISC is a member of a consortium developing the Dive Control Simulator (DCS). DCS is equipped with stunning, real-life looking graphics and dynamic simulation to train diving supervisors on various normal operations and emergency scenarios.

Diving supervisors are part of a dive support vessel crew, in charge of a diving operation. They monitor the operation and manage the panels controlling critical parameters (such as oxygen, pressure, temperature) for the divers to perform underwater tasks.

Our project partners are: PaleBlue (Stavanger, Norway) and Norsk Yrkesdykkerskole NYD (Oslo, Norway).

Wind Turbine Access System

Turbine Access Control (TAS): Design, Development and Deployment of Control System for Motion Compensated, Hydraulic, Offshore Wind Turbine Access System

We were initially contracted to assess the performance attainable for a hydraulically actuated gangway, when compensating against boat motions. This involved modelling the various sources of errors (from sensing, actuation and control performance) to achieve the target performance whilst minimising cost and complexity. We were subsequently engaged to implement the entire control system, including MMI using touch panel computers, real-time control and I/O, solving kinematics, and extensive monitoring and safety logic. Full factory testing and Sea Trials were carried out and the system was installed and on active service.

Advanced Powertrain Control Research

automotive engine

This is a rolling programme of research undertaken for a major automotive company, to investigate the modelling, estimation and model based control techniques to enhance engine control systems while meeting the increasingly tight emission regulations. Methods explored include MPC (linear and nonlinear), hierarchical strategies and hybrid control of mixed variable problems (e.g. changing number of cylinders in use). Several of the developed schemes have been tested on real engine drive cycles.
