Speed Control of Electric Motors Using New Automation Techniques

Abstract: Automation and control is used of various control systems to operate devices such as machines, industrial processes, boilers and electrostatic precipitators, to switch on communication networks, to navigate and stabilize ships, aircraft and other applications and vehicles with minimal human intervention. Some processes have been fully automated. The engine speed is controlled by the pilot as a control system. The control algorithm is implemented using a programmable logic controller. The complex motor system consists of a DC motor, a driver and a tachometer generator. The main goal is to get a satisfactory time response of the system's performance under the action of the external load. The PI controller is designed in the programming environment on a previously identified non-linear motor system. The PI controller is then integrated into the programmable controller. We will measure the speed of the motor with an incremental rotary encoder by adjusting the parameters (PLC, driver) and also reduce the overall cost of the system. Our control system is kept with the available Siemens PLC. In addition, we will monitor the motor parameters via the SCADA system.
