In this paper, an optimized proportional and derivative (PD) controller is proposed for an active suspension system. A new method to select the derivative gain is presented subject to the error and error derivative values, such that a faster response achieves mentioned to the control signal. The proportional coefficient is tuned to increase the speed of the plant response. To achieve this objective,...
This paper develops a high performance PI based controller for interior permanent magnet synchronous motor (IPMSM) drive. The performance indices which have been utilized as objective function are zero steady-state error, minimum speed deviation, and minimum settling time of the IPMSM drive. In this paper, a new method is used for tuning the PI controller. The optimal behavior of drive can be achieved...
In this paper, a new approach is proposed to tune a proportional-integral (PI) controller. By conceptual analyzing the operations of the proportional and integral parts of the controller, the design procedure is developed. Because of using nonlinear functions to tune the controller coefficients, the controller is categorized as a nonlinear PI controller. The proposed idea for tuning the PI controller...
This paper presents an Auto-tuning Smith-Predictive Proportional + Integral + Derivative (PID) controller based on Model Reference Adaptive System (MRAS). The Model Reference Adaptive Control employs the MIT rule to set the PID controller parameters on line. Smith-Predictive Control (SPC) is implied to predict the behavior of the system for presented time-delay system. Combination of the adaptive...
