Research of high precision gyro temperature control system with IMC

This work detailed discusses the design and achievement of the high precision gyro temperature control system with IMC (Inner Model Control), then analyses and verifies it, illustrates the differences between this circuit and the PID (Proportion Integral Differential) circuit for temperature control. It shows the advantages of the IMC used in H modulation (gyro angular velocity is variable) monitor inertial navigation system (Ming and Lu, 1992).
