I have recently completed an MSc in Control Systems from a top university. It seems to me that control theory must have an application within quantitative finance. I would like to apply my degree within finance, but I want to be sure that it is relevant to the role of a quantitative analyst.
The topics which I have particular interest and experience in are State Space Control, Systems Identification, Model Predictive Control and Optimal Control. I imagine that effective management of finances must involve modelling of financial systems in terms of transfer functions/state space models (based on large sets of historical data). These models could then be used to predict the evolution of a market over time, and therefore optimise a given cost function such as profit, risk etc.
If this kind of role exists within quantitative finance/ other areas, can you please give me more information/ ideas of job roles/ industries to research.
