When a system with named signals is combined with a constant system represented by a scalar or matrix, the signal names are lost. For example
ctrl = ct.rss(2, 1, 1, input='e', output='u') * 2
would be expected (by me) to have input 'e' and output 'u'. But what you get instead is
<LinearICSystem:sys[4]:['u[0]']->['y[0]']>
This is happening because scaling by a factor of 2 is internally handled by converting the number `2' into an input/output system then creating a new system that is the series composition of the two systems. But in doing that, you lose the signal names.
There is a similar problem using the series function, which also loses signal names (I would expect the input and output signal names to be preserved).
