We can provide technical support for early stage feasibility studies of control strategies or undertake troubleshooting problems for in-service or near-service control systems that are proving problematic.
We are experienced in using dynamic simulations to assess the feasibility of achieving the required control performance, by exploring different sensor types and combinations, and the most effective feedback control scheme. If the assessment had indicated that it needed something too big, too expensive or insufficient performance would result, early decisions could have been made.
Depending on applications, simulations may be built using a range of modelling packages MATLAB/Simulink, LabVIEW and the Control Design and Simulation (CD&Sim) module, etc. Models are kept as simple as possible for the purpose of evaluating dynamic performance.
We are also experienced in implementing control algorithms in full on National Instruments' suite of real-time hardware using its LabVIEW Real-Time, LabVIEW FPGA, LabVIEW MathScript RT and LabVIEW Touch Panel modules.
We can adapt individual courses to suit your company's industry/business.(Examples)
ISC was 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. ISC were then engaged to implement the entire control system, which included 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 completed. The system was installed and on active service.
ISC developed the control system for a very large pair of Gripper Arms for the jack-up vessel MPI Discovery, used to install the foundation piles for offshore wind turbines. Early simulations were used to assess the hydraulic and control designs prior to the main software development. Since this was for a working boat minimising commissioning time was critical, ISC developed a software-based emulator to allow the software to be fully tested before the mechanical build was available. It has also helped validate minor software revisions now that the system is in-service. This project was awarded the Application of the Year prize by National Instruments at their Graphical System Design Achievement Awards 2013.
Gain scheduled roll stabilisation controllers were optimised using models of vessel and wave dynamics. Our solution was tested on a nonlinear model of the vessel, and out-performed more advanced methods developed by academic groups.
