Microcomputer-based velocity control for an electro-hydraulic servo system
초록
In the microcomputer-based velocity control for an electro-hydraulic servo system, the effects of control methods and control hardware on the performance of the system were investigated. Experiments were carried out with PID and deadbeat controllers using 8 or 16 bit microprocessor and 8 or 12 bit A/D and D/A converters. It is found that the transient response of the system is better with PID controller than with deadbeat controller. When the number of bits of the microprocessor and converters are small, it is also found that amplitude quantization due to limited wordlength gives significant effects on transient responses of the system. Analytically predicted step-responses are in good agreement with experimental ones.
