Abstract
This paper presents the design and implementation of a PID controller for the speed control of a hydraulic dynamometer in a combustion engine. The controller constants were determined using the Ziegler-Nichols tuning methodology. The speed control of the hydraulic dynamometer is carried out by manipulating the volumetric flow of the working fluid (water) with a control valve, which represents the internal combustion engine load. The hydraulic dynamometer has an encoder and load cell sensors used to obtaining the main operational characteristics of the motor (torque, power and speed). Robustness tests are carried out in the controller applying disturbances in the manipulated variable to compare the different responses obtained for each P, PI and PID controller. Results indicates that by applying a PI control strategy, it can be achieving a stable state error of 0.2% and a stabilization time of 30 seconds.
