Abstract

These days OVERHEAD CRANE is widely used in different industries such as automobile, harbor, navigation and also transportation of tools in storerooms. Most models which are done through industrial dynamic systems include some vitiated parameters with NOISE and disturbance and OVERHEAD CRANE model is no exception. Disturbance in system can be due to its model or measuring tool. Kalman filter is a practical method in order to recognize the model and also filtration of disordered data. Given that OVERHEAD CRANE is a nonlinear model, asymmetric sigma-point Kalman filter improved by GENETIC ALGORITHM (GA-ASKF) is intended to estimate system parameters. One of the common ways to controlling OVERHEAD CRANE parameters is using controlling force, Bang-Bang. By the way, function of BANG-BANG CONTROLLER depends on controlling force switched times. In this paper, besides using this controller, its switched times are found by using GENETIC ALGORITHM for noisy system. The design aim is to achieve the target point in minimum time with minimum error. Also, by considering BANG-BANG CONTROLLER entrance part, the article compares the situation of the system in different mass relativeness. Simulation results shows improved performance of the GA-ASKF algorithm to determine the switching time of controller and also achieve the target point in minimum time.
