This invention discloses a sensorless multi-stage tower erection mechanism and its control method. The method includes: establishing a state machine with multi-stage action interlocking and setting a virtual position counting variable; when each stage of the multi-stage telescopic boom extends, the counting variable changes along a first direction and the hydraulic drive unit switches its speed accordingly each time the interval proximity switch is triggered, until the approach switch is triggered when the boom reaches its final position and stops; when each stage of the multi-stage telescopic boom retracts, the counting variable changes along a second direction and the hydraulic drive unit switches its speed accordingly each time the interval proximity switch is triggered, until the approach switch is triggered when the boom reaches its final position and stops. This invention utilizes only inexpensive proximity switches in conjunction with dual trigger blocks and counting logic to achieve a servo-like "slow-fast-slow" S-shaped speed curve, solving the hydraulic shock problem caused by the lack of a displacement sensor, eliminating the risk of disordered multi-stage action sequence, and achieving high safety.

This invention discloses a method and system for tracking and controlling the trajectory of an unmanned tracked vehicle on a slope based on virtual control points, belonging to the field of tracked vehicle trajectory tracking and control. First, the gravitational yaw moment caused by the vehicle's center of gravity offset is calculated, and a discrete prediction model of slope dynamics is constructed. Second, virtual control points are generated, and the influence of lateral slippage is corrected through an anti-slip compensation term. Finally, the tracked vehicle's attitude information is acquired in real time, and based on the discrete prediction model of slope dynamics, the predicted value of the state vector is obtained. The predicted coordinates of the virtual control points are calculated, and the optimal control quantity is solved. This invention innovatively proposes a dynamic migration method for "virtual control points" based on center of gravity offset and slope parameters. This method migrates the control reference point from the geometric center to a virtual position that can balance the gravitational moment, effectively solving the influence of yaw moment on the tracked vehicle's control attitude, suppressing the slippage influence caused by the lateral component of gravity, and effectively solving the instability of tracked vehicles in slope motion control.
