The boiler thermal control system is well known with the characteristic of slow time-varying, large lag and large inertia. Adopting generalized Jordan block and algebra equivalence transform method, all of the transfer functions at different load points is transformed to state-space description with time variable. According to engineering practice of control strategy based on incremental function...
A nonlinear control strategy is proposed for the three-phase three-level NPC rectifier based on the feedback linearization theory. The proposed strategy can realize the decoupled control of active and reactive current of the VSR in the d-q frame. A strategy of changing the voltage adjusting coefficient to adjust the dwelling time of the positive and the negative small vectors to control the neutral...
This paper presents a continuous sliding mode control method based on feedback linearization, an output tracking control is designed for the system. A discontinuous sliding mode control can be changed into a continuous one by dynamical extending the nonlinear system. The problem of zero dynamics from the state feedback exact linearization process can be solved by placing two integrators in front of...
This paper presents a nonlinear control strategy for unified power quality conditioner(UPQC) with better stability and dynamic performance in comparison with PI control and classical decoupled strategy. The analysis is based on the rotating reference frame, and the nonlinear property of UPQC mode is partly dealt through the exact linearization via feedback. The operation of control circuit has been...
