Problem running Gain-Scheduled Control of a Chemical Reactor example

Hello,

I'm attempting to run the 'Gain-Scheduled Control of a Chemical Reactor' example in the robust control library and get the hierarchy of errors,

Undefined variable "linearize" or class "linearize.ModelLinearizationParamMgr.getInstance".

Error in opcond.AbstractOperatingPoint/update (line 34) ModelParameterMgr = linearize.ModelLinearizationParamMgr.getInstance(this.Model);

Error in operspec (line 108) update(op,false);

Error in GainScheduledProcessExample (line 37) opspec = operspec('rct_CSTR_OL');

When searching my Matlab files, I have 6 functions called 'linearize.m'. Could it be the example is calling the wrong one? Has anyone gotten this example to run?

Thanks!

I did get this error when attempting to linearize a simulink model. Apparently, Simulink's Contol Design toolbox is necessary for this, this is a separate toolbox not included in the 'Control Systems Toolbox'.
