Trim Model to Meet State Specifications

Open the Simulink model.

mdl = 'watertank';

open_system(mdl)

Trim the model to find a steady-state operating point where the water tank level is 10.

Create default operating point specification object.

opspec = operspec(mdl);

Configure specifications for the first model state. The first state must be at steady state

with a lower bound of 0. Provide an initial guess of 2 for the state value.

opspec.States(1).SteadyState = 1;

opspec.States(1).x = 2;

opspec.States(1).Min = 0;

Configure the second model state as a known state with a value of 10.

opspec.States(2).Known = 1;

opspec.States(2).x = 10;

Find the operating point that meets these specifications.
