Laboratory Implementation Of Bang Bang Controller Based Motor Drive Module For Modeling And Control Courses

This paper describes a novel methodology for development of real-time control design and implementation of an enhanced bang-bang controller with particular emphasis on student use in a laboratory environment. The students designed and implemented their controller using a dSPACE DS1104 digital signal processor (DSP)-based data acquisition control (DAC) system, and MATLAB/Simulink environment. The controller is implemented in real-time, using the position control of a brushless drive system as a testbed. Experimental results show that the improved bang-bang controller produces adequate control performance, particularly in handling nonlinearities and external disturbances. The real-time design of the controller is integrated with previously taken lectures in linear control systems course offered every spring semester. The paper also presents a hardware platform used during the course.
