To enhance the trafficability of semi-track air-cushion vehicle (STACV), a prototype is manufactured and a heirarchy controller is designed. The control objectives are, 1) to minimize the total power consumption; 2) to follow the driver's commands and maintain the body attitude; 3) to assign and realize the generalized forces. The controller is proposed by using carefully designed controller configuration, neural network, Model Predictive Control (MPC) method, hybrid generalized extremal optimization (HGEO), etc. Finally, the effectiveness of the proposed controller is verified by experiments under two typical operation conditions.

“…Although, this vehicle has been shown to be effective when moving on the lowbearing-capacity swamp peats, some problems have been incurred during operation on swamp peat terrain due to the difficulties in controlling the aircushion system. Various different research institutions from universities, government organizations, and private companies have proposed and developed different types of tracked vehicles for transportation operation, but only for moderate terrain [2][3][4]. However, in order to be able to drive a vehicle off-road, for example in swamp peat terrain, the vehicles need lower ground pressure than ordinary road vehicles.…”

This paper presents the fuzzy logic controller (FLC) of an air-cushion system for a swamp peat terrain vehicle and describes the process by which it functions. Cushion pressure is controlled by an electronic proportional control valve and FLC using the output signal of the distance (height) measuring sensor that was attached to the vehicle. The main purpose of this study was to develop a control scheme for an air-cushion system and to investigate the relationship between vehicle vertical position and the air-cushion system, and to illustrate the important role of the fuzzy logic control system. Experimental values were recorded in the laboratory for control system testing, and in the swamp peat terrain field for vehicle performance investigation. In this paper, a fuzzy logic expert system (FLES) model, based on the Mamdani approach, was developed to predict the changes in flowrate. The mean relative error of actual and predicted values from the FLES model of flowrate was found to be slightly above the acceptable limit. The goodness of fit of the prediction values from the FLES model was found to be close to 1.0 as expected, and hence demonstrated the good performance of the developed system.

“…Therefore, transportation operation on off-road terrain are greatly emphasized to design and develop the vehicles with high crossing ability, good tractive performance and move on swamp peat terrain. Many research works have been carried out and different types of prototypes on tracked vehicle on offroad terrain have been introduced [1][2][3]. However, most of the vehicles are wheeled vehicles, tracked vehicles and aircushion semi-tracked vehicles.…”

This paper presents the fuzzy logic control system of an air-cushion tracked vehicle (ACTV) operating on swamp peat terrain. Vehicle vertical position is maintained by using an inflated air-cushion system attached with the vehicle. It is desired that the vehicle vertical position be maintained at a desired position so that vehicle obtains sufficient traction control and to propel the driving system. To accomplish this task, it is required that the error between the actual position and the desired position equal to zero, and the differential position rate also be equal to zero. Therefore, the main purpose of this study is to develop an appropriate control strategy for an air-cushion system by using fuzzy logic expert system. Air-cushion system is controlled by the electronic proportional control valve and fuzzy logic controller (FLC) with associating the output signal of the distance (height) measuring sensor attached with the vehicle. In this control scheme the fundamental goal is to employ the fuzzy logic expert system to set the fuzzy rules and to actuate the electronic proportional valve in order to obtain appropriate valve control actions. Experimental values are taken in the laboratory for control system testing to investigate the relationship between vehicle vertical position and air-cushion system.
