“…Adding a torque ripple suppression module can also effectively improve the performance of OMSS. By comparison, one of the most effective approaches is generalized harmonic injection method [ 30 , 31 , 32 , 33 , 34 , 35 ]. However, most harmonic injection schemes are implemented in rotating reference frame, and the calculation processes are often complicated.…”

The positioning accuracy and speed stability of the brushless DC motor (BLDC motor), as the drive element of the optomechanically scanned system (OMSS), are closely interrelated to the final imaging quality of the system. Active disturbance rejection control (ADRC) with strong anti-interference ability, fast response and good robustness is one of the extensively used control strategies. However, the performance of ADRC working in a complicated environment will be limited due to the controller structure, parameter tuning and the influence of multi-source nonlinear disturbance. Therefore, an improved ADRC method is proposed, which can switch between ‘point-to-point control mode’ and ‘stable speed control mode’ according to the system requirements. To further suppress the torque ripple and improve the control performance of the system, an improved harmonic injection scheme is added, and the parameters of improved ADRC are tuned by a slime mould algorithm based on a Levy flight operator (LF-SMA). The stability of the proposed ADRC is proved by Lyapunov stability theory. The experimental results show that the proposed control scheme could be available to reduce the torque ripple of the system.

“…In [13], an adaptive notch filter is used to estimate the stator current harmonics to be implemented in a multi‐reference frame, and then, by using PI regulators the stator reference voltage components in each reference frame can be derived. After that, by transformation of these reference voltages to the stationary frame and adding them, the stator voltage references are calculated.…”

Brushless Harmonic current injection to the stator windings is one of the most effective methods for torque ripple reduction of brushless DC motors. Because of multi harmonic contents of the stator currents, the conventional methods based on rotational reference frame cannot be used to calculate the voltage references for voltage source inverter. sliding mode control (SMC), which has high dynamic response to track a time varying command, can be used to force the arbitrary reference current to the stator windings without transfer the motor currents to the rotational reference frame. However, the main disadvantage of SMC is that the system states cannot reach the equilibrium point in infinite time as well as has a major chattering problem. In this paper, a new control method called integral terminal sliding mode control (ITSMC) is used to overcome these drawbacks. In order to show the robustness and performance of the proposed method, this method is compared with a SMC by some simulation and experimental tests. It is concluded that the dynamic response and robustness of the proposed ITSMC method is higher than SMC and ITSMC is an appropriate method to inject the arbitrary reference current to the motor windings.
