摘要：A continuous control system for a mining or tunnelling machine having a boom(12) with a motor driven cutting head (14) at one of its ends and a rotatable turret (20) atthe other end, the control system comprising angular encoders (40, 44) for continuouslymeasuring the angles of the boom (12) and of the turret (20) and a linear encoder (55) forcontinuously measuring the linear position of the cutting head (14), and further havingpressure transducers (P1, P2, P3, P4) for continuously measuring the pressures of thevarious hydraulic cylinders or drives (41, 43) used to operate the boom (12) and theturret (20). It may also have a power transducer (57) for continuously measuring thepower input to the motor (18) driving the cutting head (14) to control the RPM of thelatter. The signals from the above various measurements are continuously processed bya computer (46) in accordance with a predetermined computer program and a controller(47) is provided which is responsive to the computer (46) and which continuously controlsthe various parameters so as to cut a preselected profile at a predetermined depth ofcut and rate of advance.
