The conceptual side of mode switching

For continuous dynamic systems there are many powerful methods for modelling. However, when dealing with systems undergoing abrupt behavioural changes, i.e. mode switching systems, the picture suddenly is changed. We here claim that the reason for this is that mode switching traditionally is treated by mathematical and/or logical solutions only. That is, at the wrong level of abstraction. We present several arguments supporting this view, and finally present our solution to this problem: the ideal switch concept
