The controllable spark plasma sintering (SPS) process requires a stable temperature regulation to predict the microstructure evolution and densification behavior accurately. A loop feedback control algorithm called proportional integral derivative (PID) is a practical simulation method and has achieved many remarkable outcomes in regular SPS process. However, the efficiency-driven industrial manufacturing inspires the modern sintering process to be time-saving and reproducible. The modified PID controller is to be developed for the accurate temperature regulation in some demanding sintering processes. Here the variable-coefficient PID controller is introduced as a precision temperature regulation tool to substitute the inefficient “trial and error” way. The foreseeable prospect of fractional order PID control (FOPID) is also discussed as a powerful tool for the ultra-fast temperature regulation in instantaneous sintering process. These attempts are expected to open a new window for the development of advanced sintering technologies.
