“…8 and it is observed that the load distribution ratio affects the total power consumption significantly as total power consumption linearly increases with the increase of load distribution ratio. Based on previous researches [5,15], for the present IACTV, an optimal load distribution ratio of 0.2 was obtained which results in minimum power consumption of 3.5kW. Furthermore, the optimum total power consumption found from ANN was 3.42 kW which justified the above value.…”

“…Effectiveness of the developed system has emphasized the tractive performance of an intelligent air-cushion track vehicle (IACTV) [14]. To examine the proposed control system, a typical simulation case is investigated in the paper based on the established theoretical model and the designed prototype [5,10]. The effect of load distribution ratio on the total power consumption for the IACTV is shown in Fig.…”

“…However, the use of commercial intelligent air-cushion tracked vehicles to test the vehicle parameters is limited due to the difficulties in varying parameters as well as air-cushion pressure control. A small scale hybrid electrical air-cushion tracked vehicle (HEACTV) was therefore developed which offered the possibility to vary vehicle parameters in simple way based on low bearing capacity of peat swamp [5]. Aircushion system of this vehicle has been designed in such a way that it would not slide on the terrain with the vehicle movement.…”

This paper presents the control system of cushion pressure for the developed intelligent air-cushion track vehicle (IACTV) for operating on swamp terrain and wet fields. A novel auto-adjusting supporting system is designed for the vehicle's intelligent air-cushion system. Focusing on minimizing the total power demand of the vehicle, an optimization model has been established, for examining the effects of vehicle parameters and load distribution on power consumption by controlling air-cushion pressure. Then optimum cushion pressure is determined based on the developed optimum pressure -sinkage relationship and the pressure in the cushion chamber is controlled by the Fuzzy controller by maintaining volume flow rate and continuously monitored by the pressure sensor attached with the cushion chamber. The ultrasonic displacement sensor is used to measure the sinkage of the vehicle. The output voltages of the ultrasonic displacement are used to operate the pull-in solenoid switch through the microcontroller which closes the circuit of the compressor motor. Distribution of vehicle load to the air-cushion system is controlled by Fuzzy Logic controller by maintaining the inside pressure of the cushion.

A fuzzy expert system was used in this study to control an intelligent air-cushion tracked vehicle (IACTV) as it operated in a swamp peat terrain. The system was effective in controlling the intelligent air-cushion vehicle while measuring the vehicle traction (TE), motion resistance (MR), power consumption (PC), cushion clearance height (CCH) and cushion pressure (CP). An ultrasonic displacement sensor, pull-in solenoid electromagnetic switch, pressure-control sensor, microcontroller, and battery pH sensor were incorporated into the fuzzy expert system (FES) to experimentally determine the TE, MR, PC, CCH, and CP. In this study, we provide an illustration of how an FES might play an important role in the prediction of the power consumption of the vehicle's intelligent air-cushion system. The mean relative error in the actual and predicted values from the FES model with respect to tractive effort, total motion resistance and total power consumption were found to be 5.58 %, 6.78 % and 10.63 %, respectively. For all parameters, the relative error in the predicted values was found to be less than the acceptable limit (10%), except for the total power consumption. Furthermore, the goodness of fit of the predicted values was found to be close to 1.0 as expected and, hence, indicates the good performance of the developed system.

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.
