Efficiency Optimized Control of Elevator Drive
نویسندگان
چکیده
Model for efficiency optimization of electric elevator drive is presented in this paper. It combines two strategies for efficiency optimization: Loss model control and Search control. Search control technique is used in a steady state of drive and loss model during transient processes. As a result, power and energy losses are reduced, especially when load torque is significant less related to its rated value. This model is implemented in the control of real gear-less electric elevator drive with vector-controlled induction motor. Position trajectory is determined by the need that jerk is changed by the predefined function. Model of the drive is presented, and it is tested through computer simulations. Keywords-Electric elevator; Jerk control; Induction motor; Efficiency optimization; Loss model control; Search control
