Configurable control systems of power converters for instructional laboratories

Abstract

The paper discusses the design principles of configurable control systems for electric drive instructional laboratories. Adopting this approach a control structure is assembled at software level using a number of control elements and compiled into control algorithm of a real-time DSP board. To ensure comprehensive and safe test execution, all control elements operate under the supervision of a real-time system core providing protections of the motor and power converter. The improvement in reliability of hardware operation allows for an increased rate regarding power of the motors and power converters used for laboratory works. The paper also considers the requirements for configurable control systems and describes the compilation procedure including an example of code generated for nested loop field weakening control system.
