• DynamicsWe are studying discontinuous dynamical systems that exhibit the property of sliding.? A large number of systems, including large industrial polymer reactors and modelled by differential algebraic equations (DAEs) have been shown to exhibit this behaviour. The concept of equivalent dynamics has been shown to speed up sliding DAE systems by 10,000 times.
• ControlWe are looking at the control of chemical processes, especially reactors. We have effectively controlled reactors that exhibit nonlinearities and modelled by DAEs through simple controllers, such as, lead and PID.We have also successfully applied control techniques in network related applications.? We have shown that a combination of ARX modelling strategy and an adaptively detuned proportional controller chould help reduce the network traffic substantially without affecting the fidelity. We have also looked at control of systems, such as, aninverted pendulum through internet. Handling of performance deterioration through network delays is being studied.
• SimulationWe have worked on the topic of simulation methodologies and simulation environments through modern computing tools.? This approach hasbeen applied to simulation of neuro transmission in muscle cells.Automatic model derivation from first principles and data driven modelgeneration are some focus areas.
