The paper introduces a kind of optimized fuzzy-PID control method which adopts linear quadratic regulator (LQR) approach in detail. In many industrial control systems, if the model of a system is unspecific or complex, PID parameters are rather difficult to find, based on the problem this article designed the advanced controller with LQR. On the contrary with the fact that the output voltage is always...
This paper presents analysis and design control scheme including the nonlinear effects of the output-filter inductor and active switches of the inverter systems. Since the filter inductance will drop dramatically when the inverter system is operated at heavy loads, system dynamic performance will vary over a wide range. Q-parameter is selected as an input variable of the control scheme to improve...
