Mathematical model's parameters identification in a prototype of solar panel's motor

Solar panel can optimally convert energy when its position is upright to the sun, thus the innovation of solar tracker is needed. Solar tracker needs a motor so that the solar tracker is able to track the sun. This research studies a motor of solar panel prototype called motor DC. This research identifies parameter value of motor DC mathematical model. Identification is performed on resistance (R_a ), inductance (L_a ), back emf constant (K_b ), torque constant (K_m ), rotor inertia (J), coefficient of viscous friction (B). Furthermore, simulation is applied to motor DC mathematical model with the identified parameter. Simulation is repeated 4 times with combinations of back emf constant and torque constant. Result of the simulation system is angular velocity. Then, angular velocity from simulation is compared to the result of angular velocity from the experiment. Comparison indicates that the third simulation shows the best value with the confidence level of absolute average relative deviation of 97.317587123%.
