A non-cascade structure with a simple parameter adjustment method and satisfying dynamic performance is investigated so as to address the problem of complicated typical cascade control system permanent magnet synchronous motor (PMSM) system. However, current cannot work within limited value under this structure, which poses risk circuit safety. To end, fast non-singular sliding mode (FNTSM) spe...

Introduction In a cascading failure of a power transmission system, an initial event that disables a possibly small subset of the grid conspires with the laws of physics to set off a sequence of additional outages that, in the worst case, accelerates until a large subset of the network is inoperative, resulting in a significant loss of served power. The mechanics of the process can be summarize...

Traditional cascade multilevel inverter can only transmit one-direction of energy. This paper proposes a new cascade multilevel inverter topology and control strategy based on part units to realize the energy feedback. By using PWM converter to replace uncontrollable converter in part units of the traditional inverter, and combining the inverter with H-bridge inverter, the two-direction running...

This paper presents a regenerative cascade inverter topology with direct active power control scheme. From the mathematical model of the proposed regenerative cascade inverter, the instantaneous active power and reactive power are derived. Based on the instantaneous abc theory, direct active power feed-forward control is proposed to reduce AC power and voltage fluctuation in DC link. Moreover, ...

A method for PID controller tuning based on process models for series cascaded control systems using anti-reset windup technique is proposed in this paper. Closed loop response is obtained using auto tuning of PID controller. This method can be applied to any closed loop stable processes. Closed loop responses of series cascade control loops tuned by the proposed anti-reset windup technique met...

this paper develops new results on the use of model predictive control to regulate the attitude of a ground station antenna. two degree of freedom az-el pedestal is considered as ground station antenna. permanent magnet synchronous motors are taken into consideration as the best choice for satisfaction of control objectives as actuators. the design is based on a two cascade controller consist o...

An efficient one-pot nitro-Mannich/hydroamination cascade reaction for the synthesis of substituted pyrrolidines bearing three stereocentres is reported. Proceeding under the control of a combination of base and gold(I) catalysts, the cascade reaction affords the pyrrolidine products in high yields with good to excellent diastereoselectivities.
