Currently, My PH.D. Student and I using a differential Drive Mobile Robot to control it using Active Disturbance Rejection Control, We used two PMDC motors for the two wheels. But, the problem is that when we went to the data sheets to get the parameters of the PMDC motor, we did not find anything related to these parameters, like resistance, inductance, and inertia. Anybody can help us to measure these parameters experimentally. or lead us to a specific type of PMDC motor with its data sheetd that are readible.

in attachment you will find ELECTRICAL & MECHANICAL SPECIFICATIONS for PMDC Motor.

Dear Ibraheem K. Ibraheem
You can measure resistance by ohms Law method . Connect the motor to the voltage source i n series with an Ammeter.Run the motor at its rated speed. Measure the current. As we know R=V/I.This gives you the practical value of resistance for consideration.Since It has Permanent Magnet inductance varies with speed.

Hello Ibraheem,
Our freind Saif has already provided example datasheet of PMDC motors that are available from reputed commercial manufacturers. So it is better for you to look for motors from good makes or ask your supplier to provide motor datasheet.
Most specifications are already provided in the datasheet and some motors also come with CAD data which you might want to simulate before implementation.
Best wishes!
