“…The "predictive" nature of the observer refers to the fact that some of the observed quantities are evaluated at the next actuation instance (k+1) in a predictive fashion, where (k) represents the current computational time instant of the realtime digital controller [8][9]. The prediction at time (k+1) is critically important in model-based controllers for compensating the actuation delay of the digital controller.…”

Three Permanent Magnet traction motors are controlled via a unified Direct Flux Vector Control scheme. Two of the motors have the same stator with concentrated windings, one combined with a Surface Mounted PM rotor and the other with an Interior PM rotor. The third motor is a PM-assisted Synchronous Reluctance motor with distributed windings. The algorithm has a predictive nature and no regulators that need to be tuned. When switching from one motor to another, the set of motor parameters is changed and nothing else. The key parameters are the stator resistance and the dq flux linkage curves. Drive commissioning issues are addressed along with the effects of parameter errors on the control performance, and both are quite acceptable for traction applications. Experimental results are provided for all three motors.

“…Deadbeat direct torque and flux control (DB-DTFC) was developed by combining the features of deadbeat control and direct torque control (DTC) for induction motor drive systems [1,2]. DB-DTFC has been implemented for various types of electrical machine drives such as IPMSM (interior permanent magnet synchronous motor) drives [3], wound field synchronous machine drives [4], and synchronous reluctance machine drives [5].…”

“…Recently, DB-DTFC has been applied for implementation of self-sensing control [6,7] and fault-tolerant control [8]. In [2][3][4][5], it has been presented that DB-DTFC shows advantages over other motor control algorithms, for example, fast dynamic performance and less torque ripple. However, parameter sensitivity is one of the critical issues to be investigated because DB-DTFC algorithm is developed based on an inverse electrical machine model.…”

“…Equations (3)- (6) are presented as a function of stator flux linkages so that the torque In Equations (1) and (2), subscripts d and q represent the d and q axes and superscripts s and r represent a stationary reference frame and a rotor reference frame, respectively. In (2), θ is the rotor position of a PMSM, as shown in Figure 1. Applying the Clarke and Park transformation, an IPMSM model at a rotor reference frame can be derived.…”

This paper presents a stability analysis and dynamic characteristics investigation of deadbeat-direct torque and flux control (DB-DTFC) of interior permanent magnet synchronous motor (IPMSM) drives with respect to machine parameter variations. Since a DB-DTFC algorithm is developed based on a machine model and parameters, stability with respect to machine parameter variations should be evaluated. Among stability evaluation methods, an eigenvalue (EV) migration is used in this paper because both the stability and dynamic characteristics of a system can be investigated through EV migration. Since an IPMSM drive system is nonlinear, EV migration cannot be directly applied. Therefore, operating point models of DB-DTFC and CVC (current vector control) IPMSM drives are derived to obtain linearized models and to implement EV migration in this paper. Along with DB-DTFC, current vector control (CVC), one of the widely used control algorithms for motor drives, is applied and evaluated at the same operating conditions for performance comparison. For practical analysis, the US06 supplemental federal test procedure (SFTP), one of the dynamic automotive driving cycles, is transformed into torque and speed trajectories and the trajectories are used to investigate the EV migration of DB-DTFC and CVC IPMSM drives. In this paper, the stability and dynamic characteristics of DB-DTFC and CVC IPMSM drives are compared and evaluated through EV migrations with respect to machine parameter variations in simulation and experiment.

A novel direct torque control (DTC) method based on sliding-mode-control (SMC) strategy is proposed for permanent magnet synchronous motor (PMSM) which is used in electric vehicles (EVs). In order to improve the dynamic response time and enhance the robustness performance against the external loading disturbances and motor parameter's variation, a kind of SMC-based torque controller and speed controller are designed to regulate the torque angle increment and the speed respectively. The torque controller is designed based on a sliding mode controller with an asymmetric boundary layer to reduce the overshoot. Compared with other DTC methods based on space vector modulation (SVM) in the literature, the proposed DTC scheme adopts the asymmetric boundary layer SMC instead of the proportional-integral (PI) regulator. The simulation results have validated the effectiveness of the proposed SMC-based DTC method.
