Impact Time Control Guidance Law for Large Initial Lead Angles Based on Sliding Mode Control
Journal of Physics: Conference Series, 2021 In view of the interception scenario where a missile intercepts a stationary target in the longitudinal plane, an impact time control guidance (ITCG) law is proposed by utilizing the sliding mode control (SMC). An amendatory approach of t go (time-to-go)

The impact of local control timing in Ewing sarcoma
Reports of Practical Oncology & Radiotherapy, 2020 To assess the impact of delay in local control on survival outcomes of Ewing sarcoma (ES) patients.The cornerstone of therapy of localized ES includes chemotherapy and local control with surgery or radiotherapy. We sought to assess the impact of delay (>15 weeks) in timing of local control on survival outcomes of ES patients.Data of consecutive ...

Guidance Synthesis to Control Impact Angle and Time [PDF]
International Journal of Aeronautical and Space Sciences, 2006 A new guidance synthesis for anti-ship missiles to control impact angle and impact time is proposed in this paper. The flight vehicle is assumed as a 1st order lag system to consider more practical system. The proposed guidance synthesis enhances the survivability of anti-ship missiles because multiple anti-ship missiles with the proposed synthesis can
