Plant Model 0

Static gain.

The block scdpwm/Voltage to PWM/Compare To Zero causes this linearization to be

zero.

pwmblk = 'scdpwm/Voltage to PWM';

open_system(pwmblk)

The linearization is zero because the block represents a pure discontinuous non-linearity.

u = [-1:0.1:0,0:0.1:1];

y = [zeros(11,1);ones(11,1)];

plot(u,y)

xlabel('Block Input - u')

ylabel('Block Output - y')

ylim([-0.1 1.1]);
