| Summary: | The design of a good PID controller for speed control of Brushless dc (BLDC) motor is essential for its successful operation. This paper presents a design and implementation of recently developed nature inspired Flower Pollination Algorithm for speed control of BLDC motor with optimal PID tuning. In the present work, optimization based approach is applied for tuning of PID speed controller by considering an integral square error as the objective function. The effectiveness of the presented work is compared with the conventional Ziegler-Nichols method and other existing nature inspired optimization methods such as PSO and Firefly algorithms, and the same is validated through real-time implementation with dSPACE DS1103 controller board. Keywords: BLDC motor, DS1103, Flower Pollination, PID tuning
