Multi-loop PID Control Method of Brushless DC Motors via Convex Combination Method

Abstract

-This paper proposes the explicit tuning rule of multi-loop PID controller for brushless direct current motors to predict the system behaviors in time and frequency domains, using properties of the convex combination method. The convex set of the proposed controllers formulates the envelope to satisfy the performances in time and frequency domains. The final control parameters are determined by solving the convex optimization problem subject to the constraints which are represented as convex set of time domain performances. The effectiveness of the proposed control method is shown in the numerical simulation, in which controller tuning algorithm and dynamics of brushless DC motor are well taken into account.

Speed Control of Direct Current Motor Using ANFIS Based Hybrid P-I-D Configuration Controller

“…Due to the recent increase in the system's complexity, there are often challenges when tuning the PID's parameters to obtain perfect transient characteristics and stable systems. Therefore, control designers have switched to intelligent strategies to obtain optimal performance [9,10]. As mentioned, control designers have applied intelligent techniques to avoid drawbacks related to the traditional method.…”
