“…While projecting type machine has a uniform air gap, the inset and interior types have essentially salient pole construction. The power and torque expressions of salient pole motors are applicable for Variable Reluctance Synchronous Motor (VRSM) [2] also. A reluctance motor can be visualized as a salient pole motor without a field winding.…”

“…The outer loop is the speed controller, the output of which is the reference value of the torque, T e * from this value, the reference values of the current i.e., i qs * and i ds * are computed for a desired internal angle (ψ) and desired torque angle (δ). This gives flexibility in choosing the power factor of the motor from lagging to leading values including unity [2]. The field oriented control can also be obtained as a special case, by setting the power factor angle to be equal to the torque angle, resulting in complete decoupling between the armature flux and the field flux, thus producing a DC motor like behavior.…”

“…The field oriented control can also be obtained as a special case, by setting the power factor angle to be equal to the torque angle, resulting in complete decoupling between the armature flux and the field flux, thus producing a DC motor like behavior. In this sense, the proposed control scheme is more general than conventional field oriented control [2]. This paper is organized as follows: Firstly the mathematical model of VRSM is derived.…”

Synchronous motor drives are now-a-days becoming an attractive alternative to DC and IM drives, especially in the high power, low speed range. Various types of control schemes have been suggested for variable speed AC drives fed from static power sources, such as field oriented control, employing vector control strategies, has become quite popular in recent years. When this scheme is applied to a synchronous motor, the motor always operates at a lagging power factor. In this work, for the speed control loop of an inverter-fed synchronous motor drive a generalized design strategy is suggested, in which, its inherent flexibility to generate the same torque for different combinations of currents, is exploited. With that one can achieve more general types of control schemes. Existing control schemes such as unity power factor control, torque angle control as well as fieldoriented control etc. can be obtained as special cases for special types of synchronous motor such as permanent magnet and variable reluctance motors, however the details of permanent magnet motor is beyond the scope of this paper. The closed loop system for the Variable Reluctance Synchronous Motor is simulated using MATLAB. The performance figures of various cases such as unity power factor control, torque angle control and field oriented control can be obtained and verified through simulation for different power factors of the motor ranging from lagging to leading including unity

“…1) is that the dynamics of the current controller is sufficiently fast, so that no (1) appreciable change in the speed takes place during its tran- (2) sient phase. This has to be ensured by design and implies that (3) the closed loop bandwidths of these two loops must differ by (4) at least a factor of ten.…”

Synchronous motor drive3 are fast becoming an attractive alternative to dc and induction motor drive3~especially in the low speed~high power range. Different types of control schemes have been suggested for variable speed AC drives fed from static power sources. Among them, field oriented control enploying vector control strategies has become quite popular in recent years. A disadvantage of the schenle when applied to~ynchronous motor drives is that the motor alw~ys~perates at a lagging power factor. In this work~a generalized design strategy is sug~ted for the speed control loop of an inverter-fed synchronous motor drive~in which~its inherent flexibility to generate the same torque for different combinations of currents, is exploited that can achieve more general types of control. Existing control schemes such as unity power factor control, torque angle control, as well as field-oriented control etc can be obtained as special cases for special types of synchronous motor such as permanent magnet and variable reluctance motors~however the details of pennanent magnet motor is beyond the scope of this paper. The scheme has been validated through extensive simulations as well as laboratory experiments.

“…In [2], a method of estimating the currents in the damping windings is proposed in order to allow their inclusion within a field oriented controller while a generalized vector control strategy is developed for a current-fed salient pole synchronous machine with dampers. In [1], a nonlinear control scheme consisting of two nested loops for speed and currents control is designed, which is validated by experimental results.…”

We design a nonlinear adaptive output feedback control for synchronous motors with damping windings, which, for any motor initial condition, for any unknown constant load torque within known bounds and for any uncertain motor inertia within restricted bounds, guarantees: i) asymptotic rotor speed tracking of arbitrary smooth reference signals; ii) exponential tracking for the rotor flux vector direct axis component of suitable smooth reference signals; iii) exponential regulation to zero of the stator current vector direct axis component (motor field orientation).
