چکیده
The problem of speed control of a permanent magnet synchronous motor (PMSM) with unknown parameters and unknown external load torque is formulated and solved as an adaptive control problem that meets the requirements of asymptotic command following with simultaneous asymptotic disturbance attenuation. The key point is to identify the system without knowledge, estimation or measurement of the unknown disturbance. The satisfactory performance of the results is illustrated through application of the proposed nonlinear dynamic controller to a PMSM for three cases: first, no external load torque; second, smoothly starting steady external torque; third, unknown noisy and fast varying load torque.

However, disturbances, such as wind speed, affect the performance of wind turbines, and as a result, the use of various types of controller becomes crucial.This paper deals with two ada...
متن کاملAn Improved Continuous-Time Model Predictive Control of Permanent Magnetic Synchronous Motors for a Wide-Speed Range
This paper proposes an improved continuous-time model predictive control (CTMPC) of permanent magnetic synchronous motors (PMSMs) for a wide-speed range, including the constant torque region and the flux-weakening (FW) region. In the constant torque region, the mathematic models of PMSMs in dq-axes are decoupled without the limitation of DC-link voltage. However, in the FW region, the mathemati...
