Model Linearization

The operating points are now ready for linearization. First specify the input and output

points using the commands:

io(1) = linio('scdspeed/throttle (degrees)',1,'input');

io(2) = linio('scdspeed/Spark Advance',1,'input');

io(3) = linio('scdspeed/rad//s to rpm',1,'output');

Linearize the model and plot the Bode magnitude response for each condition.

sys = linearize('scdspeed',op,io);

bodemag(sys)
