Step Three – Setup MATLAB

First you will start MATLAB, and then you will create a simulink model for control system design. You will use the antenna model files from the last section, plus several additional files.

To start MATLAB:

1. Start MATLAB in the same directory as the one the model and Simulink files reside.
2. Set up the MEX utility, if not already set up.
Enter mex -setup from the MATLAB command window, and then select the appropriate compiler. (see http://www.mscsoftware.com/Support/Platform-Support/Default.aspx under Hardware & Software Requirements for a list of supported compilers)
3. At the prompt (>>), type ant_test.
MATLAB displays:
%%%INFO:Adams plant actuators names:
1 control_torque
%%%INFO:Adams plant sensors names:
1 rotor_velocity
2 azimuth_position.
4. At the prompt, type who to view the list of variables defined in the files.
MATLAB displays the following relevant information:
 
ADAMS_cwd
ADAMS_inputs
ADAMS_poutput
ADAMS_sysdir
ADAMS_exec
ADAMS_mode
ADAMS_prefix
ADAMS_uy_ids
ADAMS_host
ADAMS_outputs
ADAMS_solver_type
 
ADAMS_init
ADAMS_pinput
ADAMS_static
 
You can check any of the above variables by entering them at the MATLAB prompt. For example, if you enter Adams_outputs, MATLAB displays all of the outputs defined for your mechanism. For example:
ADAMS_outputs = rotor_velocity!azimuth_position
