OP wrote (a):

All you need to do is assign an identifier for the tab, for example, the following code:

Ext.define("appName.view.Main", { extend: 'Ext.tab.Panel', id: 'mainTabPanel',

Then use the following code to extract this tab and set the active item

Ext.getCmp('mainTabPanel').setActiveItem(1);

Hope this helps someone

only for those who are looking at this, you can pass in the index, panel identifier or the panel object itself to set the active element
