High-precision modeling control method of inertial platform type gravimeter temperature control system

The invention discloses a high-precision modeling control method of an inertial platform type gravimeter temperature control system. The method is used to improve temperature control precision of a platform body, a gyroscope and a gravity sensor in a sea-air gravimeter to be superior to 0.01 DEG C so as to meet a high-precision measurement requirement of the sea-air gravimeter, and comprises the following steps of 1, modeling a temperature control object; 2, forming a temperature control method; and 3, setting temperature control parameters. Advantages of the invention are that aiming at adverse factors such as a compact structure, serious temperature coupling and the like of each temperature control object of the platform body, the gyroscope and the gravity sensor in a sea-air gravimeterplatform, through accurate modeling of the temperature control object and a non-linear control method, high-precision temperature control of three channels of the platform body, the gyroscope and thegravity sensor is achieved
