Our motor control library is a collection of essential functions that you can use as building blocks to implement Field Oriented Control (FOC) of 3-phase motor control applications on dsPIC ® Digital Signal Controllers (DSCs).
During startup stage of short-term acceleration system such as continuous shock test, high power induction motor draws dramatically high current in a short time
In this paper, for high-power flywheel energy storage motor control, an inverse sine calculation method based on the voltage at the end of the machine is proposed, and angular compensation can be performed at high power, which makes its power factor improved.
Mechanical elastic energy storage (MEES) system completes the energy storage process through permanent magnet synchronous motor (PMSM) rotates and tightens the energy storage boxes which contains
The control strategy is used to test and simulate the machine-side converter that has been built. The results show that the proposed control strategy is reasonable and effective.
The control system of an external loop of speed and an internal loop of current is adopted at the motor side. The standard ADRC is adopted by increasing the new nonlinear control function.

Accordingly, an improved adaptive sliding mode observer algorithm for the charging and discharging control of the flywheel energy storage system is proposed.
In the charging mode, the double-loop control strategy, including the outer speed loop and the inner current loop, is used to control the speed of the MS-FESS at the motor state.
Therefore, this paper references the approach of high-power hybrid energy systems in automobiles and proposes a battery–supercapacitor hybrid energy storage system (BSHESS) and energy management strategy.
Therefore, sensorless control technology is preferred. Furthermore, the PMSM is the core of energy exchange in the flywheel energy storage system, and the accuracy and speed of the motor control strategy determine the overall charging and discharging control performance of the system.
Most current research on SMO algorithms primarily focuses on motor control 30, whereas flywheel energy storage systems exhibit a more complex back-to-back structure, high operational speeds of the flywheel and motor, large system inertia, fast charging and discharging rates, and frequent switching of control strategies 31, 32.
Block diagram of the machine-side charge and discharge control of the flywheel energy storage system. The grid-side control strategy of the flywheel energy storage system combines grid voltage-oriented vector control and SVPWM (Space Vector Pulse Width Modulation) technology.
The control strategy on the motor side is the speed external loop and the current internal loop. The PI controller is replaced with the ADRC controller. Considering the high real-time requirements of the system for the current internal loop, the PI controller is still used for the current internal loop.
Most of the inverter drive control technologies can be adapted and applied to the charging and discharging control of the flywheel energy storage system, but they need to be modified and improved in conjunction with the operational conditions of the flywheel itself.
The magnetically suspended flywheel energy storage system (MS-FESS) is an energy storage equipment that accomplishes the bidirectional transfer between electric energy and kinetic energy, and it is widely used as the power conversion unit in the uninterrupted power supply (UPS) system.
