Parameters vary with time due to the depreciation and aging effect which reduces performance, therefore, to overcome this problem, motor parameters should be updated and different techniques should be used for this purpose. All the previously developed methods are built upon parameter knowledge of the accurate model.
The techniques presented in the literature are much complex and require huge computational costs making these unattractive for common DC servo motor parameter estimation purposes. The contributions of the article are summarized as:
(1) The first-principle model of the DC servo motor is developed and comparing coefficients method has been used to determine the system parameters.
(2) The parameter estimation toolbox has been used to estimate the parameters and validate the response of the system.
(3) A system identification toolbox has been used to estimate parameters.
(4) Comparison of the three methods has been carried out to select the best option for such applications.
Experimental data has been used for the comparison of the estimated response from the techniques. The results show that the parameters obtained from the parameter estimation method give the most accurate simulation results with the least error against the experimental results.

A plot of T/T_M versus ω/ω_M characteristics with V_T/V_Tm as a parameter is shown in the following picture. The curves are non-dimensionalized and based on Eq. (11).
The curves can be dimensionalized if the manufacturer's data for a particular motor are known. For example, a DC servo motor has an armature resistance of 5 ohms and a no-load speed of 3000 rpm at a maximum armature terminal voltage of 90 volts.
To dimensionalize a plot of T/T_M versus ω/ω_M characteristics, find the value of no-load speed
ω_M in radians/sec and the value of stall torque T_M.
From Eq. (1), ω is defined as 2ω X rpm/60. At no-load speed, ω= ω_M which is:
ω_M= 2π X 3000/60
= 314 radians/sec

When choosing a servo motor, it is important to have a good understanding of the system to be controlled. In DC servo motor operation, the control algorithm is paramount to the improvement of transient response times reduction of steady-state errors, and sensitivity to load parameters.

Servo control can generally be broken down into two classes of problems: Command tracking and disturbance rejection. The first pertains to how well the actual motion follows the position, velocity, acceleration, and torque commands. The second can include anything from torque disturbance on the motor shaft to supply voltage variations.

PID (Proportional Integral and Derivative) and PIV (Proportional Integral and Velocity) loops are the most common controller strategies employed. Unlike Feed-Forward control, which can anticipate the internal commands for zero error following, disturbance rejection reacts to unknown disturbances and modeling errors. To improve the overall performance, both of these control types can be combined.

The servo control technique is one of the key technologies in the field of control like robots. In order to meet the demands of servo control for robots, a DSP-based DC servo motor control system was developed. Firstly, this paper promoted the design of the controller an danalyzed the overall structure and function of the system. Then the hardware of the system was introduced and the key components were chosen and demonstrated; the classical PID algorithm was selected as the core algorithm of servo control and the design of the system program was elaborated. Finally, an experiment was conducted on the hardware platform with software systems.

A DC servo motor along with servomechanism acts as a servo motor which is basically used as a mechanical transducer in the automation industry. Based on its accurate closed-loop control, it has versatile applications used in many industries. The DC servo motor definition is, a motor that is used in servo systems is known as a servo motor. A servo system is a closed-loop system where the feedback signal (position, velocity, acceleration, etc.) drives the motor. This signal acts as an error and based on controller, accurate position or velocity is achieved. The motors are coupled to an output shaft through a gear train for power matching.
