The 'zero deformation' intelligent control system for buildings involves connecting a drive system and an intelligent control system to the main structure; the drive system includes a power source, actuators, thermistors, temperature sensors, and intelligent anchoring devices. The power source uses shape memory alloy material and is arranged outside the structural components, with possible configurations being straight lines, zigzags, or curves, anchored at both ends by the intelligent anchoring devices to the main structure. The actuators form a closed loop with the power source through wires, used to drive the power source. Thermistors are fixed on the power source and connected to temperature sensors. The intelligent control system includes a force state monitoring instrument and a computer control system. The force state monitoring instrument is installed at the control section of the main structure and is connected to the drive system via the computer control system, forming a closed control loop. The computer analyzes and processes the force information of the structural components. And control the actuation of the drive system. Can precisely control the deformation of the building.
