In general, the Electronic forklift ,driven by DC motor drive system is used in the industrial field. Classically, the DC motor is controlled by current or speed control using proportion control method, by output torque following the load on the plane like a manual operation. But in the industrial field, the Electronic forklift is demanded the robust drive mode. Some cases of the mode, there are trouble in torque and speed control following slope capacity. The control is sensitive concerning with slope angle and output speed, various control method is studied for stability of speed control. In this paper, I apply speed controller for the self-tuning using the genetic algorithm to obtain robust, stable speed control.and use stable, high efficiency control using DSP as main controller for high speed processor, embody dynamic characteristic of control compared the PI control to the fuzzy control.

Hydraulic manipulators have been widely used in many different fields due to their high force/torque to inertia ratio. The increased speed of hydraulic manipulators requires solutions to problems ranging from mechanical design to the need to determine a robot model suitable for model-based control. As a solution, this paper presents the integration of SolidWorks with Simscape for designing and controlling hydraulic manipulators. The integration provides a platform for the rapid control prototyping of a hydraulic robot without the need to build actual prototypes. The mechanical drawings of a manipulator are first created using Solidworks and are then imported into Simscape, where the manipulator is represented by connected block diagrams based on the principle of physical modeling. Simulation examples for a 3D manipulator made by KNR SYSTEM INC are verified to show the effectiveness of the presented platform.
