Coupled Electric Drives

The coupled electric drives consists of two electric motors that drive a pulley using a flexible belt. The pulley is held by a spring, resulting in a lightly damped dynamic mode. The electric drives can be individually controlled allowing the tension and the speed of the belt to be simultaneously controlled. The drive control is symmetric around zero, hence both clockwise and counter clockwise movement is possible. The focus is only on the speed control system. The angular speed of the pulley is measured as an output with a pulse counter and this sensor is insensitive to the sign of the velocity. The available data sets are short, which constitute a challenge when performing identification.
