Optimal-and-Robust Control Strategy Decoupling Torque and Magnetic-Flux for IM by IRM-ILQ Design Method

Today, with the increase in greenhouse gases, the global environment has deteriorated. Terrible droughts and floods frequently break out among many parts of the world. In order to control the increasing greenhouse gas, renewable energy power generation such as wind power and solar energy has to be introduced rapidly.In this paper, a new optimal-and-robust control strategy, decoupling torque and magnetic flux of IM (Induction Generator and Motor) by ILQ (Inverse Linear Quadratic) design method with IRM (Inverse Reference Model), is proposed. Proposed method provides robust and independent optimal control of torque and magnetic flux even when the environment around the generator in such as wind generation changes.
