This paper presents a detailed tracking based control design for toolface (TF) positioning on a rotary steerable drilling system (RSS). The RSS uses hydro-electromechanical actuators for real-time bit orientation during directional drilling. Key requirements of the RSS are to adjust the TF quickly and smoothly to track the TF command, and to maintain the TF(More)
Clutch shift control is critical for the performance and fuel economy of automotive transmission, including both automatic and hybrid transmissions. Among all the factors that influence clutch shift control, clutch fill and clutch engagement are crucial to realize a fast and smooth clutch shift. When the clutch is not engaged, the fluid held by the(More)
This paper focuses on the stabilization of an internal model based control system for reference tracking/disturbance rejection, where the physical plant is linear time invariant while the generating dynamics of the reference/disturbance is time varying. Given the inevitable linear time varying (LTV) nature of the internal model unit resulting from the time(More)
This paper focuses on the design of a low order robust stabilizer for the tracking/disturbance rejection problem based on the internal model principle in the time-varying setting and its application to the hydraulic pressure tracking with varying frequency. The problem of this kind known as output regulation generally consists of two major parts: internal(More)
