Its sensitive element is a vibratory-like Chinese traditional bell, using a piezoelectric element on the wall of the vibrator to detect the standing wave\u2019s precession to solve the input angular rate. This work mainly studies the circuit system of a bell-shaped vibratory angular rate gyro. It discusses the process of circuit system design, analysis and experiment, in detail, providing the foundation to develop a bell-shaped vibratory angular rate gyro. Since the bell-shaped resonator\u2019s curved structure has the characteristics of large noise in the piezoelectric signal and large harmonics, this paper analyzes its working and signal detection method, then gives the whole plan of the circuit system, including the drive module, the detection module and the control loop. It also studies every part of the whole system, gives a detailed design and analysis process and proves part of the circuit system using digital simulation. At the end of the article, the test result of the circuit system shows that it can remove the disadvantages of the curved structure having large noise in the piezoelectric signal and large harmonics and is more effective at solving the input angular rate.<\/jats:p>","DOI":"10.3390\/s140305254","type":"journal-article","created":{"date-parts":[[2014,3,13]],"date-time":"2014-03-13T12:23:28Z","timestamp":1394713408000},"page":"5254-5277","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Research on the Signal Process of a Bell-Shaped Vibratory Angular Rate Gyro"],"prefix":"10.3390","volume":"14","author":[{"given":"Zhong","family":"Su","sequence":"first","affiliation":[{"name":"School of Automation, Beijing Institute of Technology, Beijing 100084, China"},{"name":"Beijing Key Laboratory of High Dynamic Navigation Technology, Beijing Information Science & Technological University, Beijing 100101, China"}]},{"given":"Ning","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Automation, Beijing Institute of Technology, Beijing 100084, China"},{"name":"Beijing Key Laboratory of High Dynamic Navigation Technology, Beijing Information Science & Technological University, Beijing 100101, China"}]},{"given":"Qing","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of High Dynamic Navigation Technology, Beijing Information Science & Technological University, Beijing 100101, China"}]},{"given":"Mengyin","family":"Fu","sequence":"additional","affiliation":[{"name":"School of Automation, Beijing Institute of Technology, Beijing 100084, China"}]},{"given":"Hong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Automation, Beijing Institute of Technology, Beijing 100084, China"},{"name":"Beijing Key Laboratory of High Dynamic Navigation Technology, Beijing Information Science & Technological University, Beijing 100101, China"}]},{"given":"Junfang","family":"Fan","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of High Dynamic Navigation Technology, Beijing Information Science & Technological University, Beijing 100101, China"}]}],"member":"1968","published-online":{"date-parts":[[2014,3,13]]},"reference":[{"key":"ref_1","unstructured":"Matveev, V., and Basarab, M.
