Advanced Bike Dynamics Control System Design Recommendations

This block diagram representation delves into PID control for bike dynamics control, emphasizing actuator R(s) and sensor Θ(s). Expert advice from professors, colleagues, and professionals like Professor George Mansfield and Dr. Matthew Graham is included in the suggestions for current and alternative designs. Inputs from specialists in mechatronics, mechanical engineering, and controls offer insights into implementing front wheel manipulation, gyroscope stability, and other sensor and software recommendations for this project. The revision aims to achieve faster response times and a robust design, potentially necessitating a controller redesign.

  3. Previous Design

  4. Advice: Professors, Colleagues, and Professionals • Suggestions of Current Design • Professor George Mansfield MS Control Systems • Implementing sand paper and rubber wheel to simplify design. • Bode Analysis for determining PID values. • Dr. Matthew Graham Ph.D Control Theory • Instead, using a horizontal pendulum to shift CG. • Root-Locus design techniques for PID controller.

  5. Advice: Professors, Colleagues, and Professionals • Suggestions of Other Designs • Dr. Key Moon Specializes in Mechatronics • Using front wheel manipulation as primary control system. • Extruding a rod from the frame with training wheels for mechanical safety. • Steve McFadden and Others ME Students • Implementing a gyroscope to achieve stability. • A robust design but would require a lot of power/torque • GunnarRistrophIJK Controls • Also suggested front wheel manipulation. • Suggested types of sensors and software recommendations (AVR Studio) • John Berkeley PE Otte-Berkeley Group • Also suggested front wheel manipulation. • Dr. MortezaMehrabadiPh.D Mechanical Engineering • Listen to Dr. Moon

  6. Fail Early, Fail Often • Abandoning the pendulum design • Problems include • Reaction forces • Control opposite of theory • Response time • Instead focusing on other designs, primarily: • Only front wheel manipulation • Gyroscope

  7. Revised Goals for Semester • Determine CG • Rig to suspend bike • Intersecting line method • Guess and Check • Dynamics of machine are not well defined • Determine if controller redesign is necessary • Faster response time

  8. Next Week • Finalized design • Decision on Gyroscope design • Rework electronic to get it to turn on • Examine current state of data logging
