Abstract
- This paper proposes a real-time hybrid fuzzy bang–bang (BB) controller with switching function, in order to implement a full nonlinear control law. The controller consists of a fuzzy-BB controller in parallel with a BB controller while the system is in operation. In order to circumvent the shortcomings of fuzzy-BB and BB-based controllers, a hybrid fuzzy-BB controller is proposed, in which the output can be either the outputs of the two, i.e., the fuzzy-BB or BB units that are being switched as per the absolute error signal. Normally, the BB controller operates in general; the fuzzy-BB controller is activated when the drive system experiences oscillatory behavior. The choice between the fuzzy-BB and BB controllers is based on a set of simple <sc>if–then</sc> rules; the overshoot and the oscillatory behavior have to be detected by the absolute errors. Trajectory tracking of nonlinear motor drives in position mode serves as a test bed for the control law, and a real-time experiment allows for the assessment of its practical applicability. The hybrid fuzzy-BB controller has been implemented on hardware with a dSPACE digital signal processor, and it is observed that the performance of the controlled brushless dc motor drive with the hybrid fuzzy-BB controller is assuring. Noticeably, experimental results demonstrate that the proposed controller is capable of significantly cultivating the motor performance under random disturbance and different loading conditions.
