“…The backstepping control is used to decompose the complex nonlinear system into subsystems that do not exceed the system order, then design the corresponding Lyapunov function and intermediate virtual control quantity for each subsystem [30]. At each stage, the current Lyapunov function will be based on the state of the previous subsystem, including the current virtual control quantity to ensure system stability [31]. The control steps are mainly divided into the following steps: Firstly, the controller selects some states of the system as subsystems and designs the Lyapunov functions.…”

The traditional sensorless control system of permanent magnet synchronous motor (PMSM) has the problems of low estimation accuracy and poor anti-interference ability. Moreover, the position estimation performance is subjected to position harmonic ripples caused by inverter nonlinearities and flux spatial harmonics. To optimize the dynamic performance of the PMSM sensorless control system, this paper proposes a sensorless control scheme that combines integral backstepping control with enhanced linear extended state observer (ELESO). The ELESO consists of two linear extended state observers (LESOs), which estimate the internal and external disturbances of the system, to improve the estimation accuracy of rotor position. Then, the integral backstepping controller processes the estimated rotor position and speed information to obtain d and q-axis voltages. The sensorless control scheme is implemented in the Matlab/Simulink and verified by experiments. The simulation and experiment show that the scheme can effectively suppress load interference and improve control accuracy.

“…However, maintaining fast dynamic performance under 𝑞-axis current constraint is seldom considered in existing PCH-based PMSM control methods. To enhance the performance of the system, integral action (IA) is always used in the controllers to eliminate static differences, unmatched disturbance and other phenomena ignored by the model assumptions in industrial applications [20]- [21]. In [22], the integral action of the IDA-PBC method was added in PCH system (IAPCH) by coordinate transformation and increasing dimensions, and then, a speed regulation controller was designed for the PMSM.…”

To ensure overcurrent protection, fast dynamic performance and good robustness, a novel speed regulation controller is proposed. The interconnection and damping assignment passivity-based control (IDA-PBC) of Port-controlled Hamiltonian (PCH) systems has the advantages of simple structure and explicit physical meaning. On account of fast dynamic performance and 𝑞-axis current-constraint are contradictory, this paper presents a current-constraint speed regulation method for the permanent magnet synchronous motor (PMSM) based on port-controlled Hamiltonian (PCH) realization and deep deterministic policy gradient (DDPG) to balance them. First, a modified IDA-PBC controller with integral action(IA) is constructed, which can regulate the speed and the current of the PMSM simultaneously, and be more suitable for practical applications due to the addition of IA. For both current-constraint and fast dynamic performance, the reinforcement learning of DDPG is utilized to find the optimal parameters of the controller. Finally, experiments are carried out to verify the effectiveness and robustness of the method.

The purpose of this paper is to propose a new control technique for an interior permanent magnet synchronous motor that has been designed using a modified integral backstepping controller. This architecture consists of a nonlinear backstepping control scheme to achieve the purpose of speed tracking. Then the nonlinear controller based on the backstepping control scheme with the introduction of integral actions is designed for the IPMSM drive system. The suggested controller is not only designed to stabilize the interior permanent magnet synchronous motor system, but also to ensure that the speed tracking error converges asymptotically to zero in the existence of system uncertainties and external disturbances. The advantage of the suggested approach is that the proposed controller guarantees good tracking performance, reduces steady-state errors, robustness against all parameter uncertainties, and load torque disturbances in the interior permanent magnet synchronous motor system. A new speed control scheme for the design of the interior permanent magnet synchronous motor is being developed in this work. To show the feasibility of the suggested approach, the experiment is carried out with a real-time interface based on dSPACE. A comparison with the proportional-integral controller has been made. The results prove that the proposed backstepping controller has a rapid transient response and strong robustness for all disturbances under different conditions.
