Linearize the plant at the model operating point.

blockpath = 'magball/Magnetic Ball Plant';

linsys = linearize(mdl,blockpath);

View the default state order for the linearized plant.

linsys.StateName

ans =

3x1 cell array

{'height' }

{'Current'}

{'dhdt' }

Linearize the plant and reorder the states in the linearized model. Set the rate of change

of the height as the second state.

stateorder = {'magball/Magnetic Ball Plant/height';...

'magball/Magnetic Ball Plant/dhdt';...

'magball/Magnetic Ball Plant/Current'};

linsys = linearize(mdl,blockpath,'StateOrder',stateorder);

View the new state order.
