说明: 某厂向用户提供发动机,合同规定,第一、二、三季度末分别交货40台、60台、80台.每季度的生产费用为 (元),其中x是该季生产的台数.若交货后有剩余,可用于下季度交货,但需支付存储费,每台每季度c元.已知工厂每季度最大生产能力为100台,第一季度开始时无存货,设a=50、b=0.2、c=4,问工厂应如何安排生产计划,才能既满足合同又使总费用最低.讨论a、b、c变化对计划的影响,并作出合理的解释(To provide users with a factory engine, contract, first, second and third quarter respectively, delivered at the end of 40, 60, 80. Quarterly cost of production (million), in which x is the quarter of the number of production. If the remaining after delivery, can be used for delivery next quarter, subject to payment of storage fees, for each element c of each quarter. The largest known plant production capacity of each quarter to 100, the beginning of the first quarter of stock, set up a = 50, b = 0.2, c = 4, asked how to arrange the production of the factory plans to meet the total cost of the contract makes the minimum . Discussion of a, b, c of the impact of change on the plan and make a reasonable explanation)

Electric-Wheelchair-Demo
An electric wheelchair uses a motor with a torque constant of 1.1 Nm/A, powered from a 24 V
battery, with an internal resistance of 0.25Ω. We are interested in designing a controller with 44
Nm continuous torque capability, both in driving and braking modes at all speeds, with the
widest possible operating speed range, both forward and reverse direction using the given
battery.
