A nonlinear system has an input-output model given by:

1. y'(t) + [1 + 0.2y(t)] y(t) = u(t) + 0.2u(t)3

i) Compute the operating point(s) for uo=2

ii) Obtain a linearized model for each of the operating points above.

2. Ã Â¿(t) + y(t) Ã Â½(t) + y(t)3 − y(t) = 2Ã Âº(t) + u(t)2

iii) Compute the operating point(s) for uo=√6

iv) Obtain a linearized model for the operating points above.
