    Behavioural model
    - The behavioural approach to systems theory and control theory was initiated in the late 70's by J. C. Williams as a result of resolving inconsistencies present in classical approaches based on state-space, transfer function, and convolution representations.

    - This approach is also motivated by the aim of obtaining a general framework for system analysis and control that respects the underlying physics.

    - The main object in the behavioural setting is the behaviour --- the set of all signals compatible with the system.

    - An important feature of the behavioural approach is that it does not distinguish a priority between input and output variables.

    - Apart from putting system theory and control on a rigorous basis, the behavioural approach unified the existing approaches and brought new results on controllability for nD systems, control via interconnection, and system identification.
