Application of Multistage Speed Control Strategies in Research on Properties of Hydro-Mechanical Power Split Transmission

Abstract

The drive principle of Hydro-mechanical Continuously Variable Transmission (HMCVT) are demonstrated in this paper. Afterwards, the control system, which attempt to realize the experiment purpose, is proposed. This paper is based on theoretical analysis, a feasible scheme for this test is proposed, the object which should be controlled and the data which should be collected in the whole process are explicated. Furthermore, MATLAB/Simulink are used to simulate the peculiarity of the pivotal object which is included in the test, different control tactics are taken according to different objects. The PAC System RX3i are used in the test as the controller. Finally a better multistage speed control strategy is introduced which based on the comparison of the result both in theory and experiment.
