Electric Drive System for Speed Adjusting of a Three-Phase Asynchronous Motor using a PLC for propelling an electric vehicle

The purpose of designing this system is to regulate the speed of three-phase asynchronous motor of the platform in three ways: automatically (in this way speed profile is a profile imposed by the user at the beginning of motor start), manually (in this way speed profile can be chosen either from the potentiometer, or the display panel HMI) or in "GSM" (in this way, the GPRS module receives the SMS from a user using a mobile phone).
