Abstract

Mode-based control design of the sledge system of a BeoSound 9000 CD-player system produced by Bang & Olufen A/S is discussed. The sledge system is modeled theoretically and then system coefficients are identified through experiments. The obtained model is validated. Several control methods, namely digital PID control, digital PI control with anti-windup, and observer-based state feedback with integral control, are developed and then implemented in a TI MSP430F149 microprocessor. The test results show that both systems controlled by the digital PI control with anti-windup and the observer-based state feedback with integral control satisfy requirements defined by the industrial partner -Bang & Olufsen A/S.
