“…In both the investigated and conventional DTC schemes, the reference torques are generated by the PI speed controllers, where the parameters are set to k pv = 0.6 and k iv = 1. The parameters of the torque and flux PI controllers are designed according to equations (17), (18), (25), and (26), where k pT , k iT , k pc , and k ic are designed to meet the natural angular frequency v n = 600 rad/s and damping coefficient z = 1. The coefficient k(T) could simplify to k T , since the torque angle changes little when the used PMSM is running at the rated condition.…”

“…Advanced control theories such as the feedback linearization method, the sliding mode method, and the back-stepping method are used to design torque and flux controllers because they can make use of the nonlinearity of PMSM. 14–22 However, these methods need massive calculation to obtain the control law that ensures the stability of the PMSM system; meanwhile, the control structure becomes complex and control parameters are not easy to adjust. In addition, the proportional and integral (PI) controller, which is implemented intelligibly with an intuitive meaning, is an effective way of control instead of using the hysteresis controller.…”

This study investigates the direct torque control strategy of permanent magnet synchronous motor with the space vector modulation, on account of large torque fluctuation and varied switching frequency of classic direct torque control strategy. The relationship among the terminal control voltages and the torque and stator flux of the permanent magnet synchronous motor is derived through the dynamic model of motor. Accordingly, the torque and the flux closed-loop feedback control structure are established, where the error signals are regulated by the proportional and integral controllers to generate output voltages. Furthermore, the parameters of the controllers are designed through explicitly analyzing the frequency domain models of the torque control loop and the flux control loop. The accurate calculation formula of control parameters, which has both explicit setting target and definite physical meaning, is obtained. Therefore, the design of torque and flux controller parameters becomes easy in the direct torque control with space vector modulation technology, and satisfactory flux and torque control can be acquired. Finally, simulation and experimental tests are demonstrated in support of the validity of the investigated scheme and the feasibility of the proposed controller parameter design.

“…Over some backward steps, one or more virtual control variables are designed to transform a high-dimensional nonlinear plant into a low-dimensional linear plant. Currently, backstepping control has been successfully applied to the PMSM in the areas of vector control 27,28 and direct torque control, 29 but it is rare to find backstepping control to suppress the vibration of the flexible load while improving the system's operation efficiency.…”

The operational performance of the spiral spring energy storage system is affected by the vibration of the spiral spring and the electrical loss of the permanent magnet synchronous motor. It is important to eliminate vibration and reduce electrical loss. A unified control scenario for speed regulation and vibration suppression based on the minimum electrical loss is proposed. First, the spiral spring is equivalent to an Euler–Bernoulli beam and its dynamic model suitable for control is established via the Lagrange equation. Then, the unified control scenario is proposed through nonlinear backstepping control. The speed controller and current controller including modal vibration suppression and minimum electrical loss operation of the system are established, and the stability of the controller is theoretically proved. Moreover, for unknown vibration mode of the spiral spring, a vibration mode–based estimation method with the least-squares algorithm is designed. Aiming at the uncertainty of the permanent magnet synchronous motor’s iron loss resistance, an estimation algorithm based on an adaptive neural fuzzy inference system is designed. The experimental results verify the correctness and effectiveness of the proposed control scheme. In comparison with traditional backstepping control, the proposed control method can effectively suppress the vibration of the spiral spring and realize the stable and highly efficient energy storage operation of the system.
